mapping of proteolytic fragments generated by meprinbeta from the chicken tenascin-C and the human recombinant 250 kDa TN-C variant. In chicken tenascin-C, meprinbeta processes all three major splicing variants by removal of 10 kDa N-terminal and 38 kDa C-terminal peptides, leaving a large central part of subunits intact. A similar cleavage pattern exists for large human tenascin-C variant where two N-terminal peptides of 10 and 15 kDa and two C-terminal fragments of 40 and 55 kDa are removed from the intact subunit. N-terminal sequencing reveals the exact amino acid positions of cleavage sites. In both chicken and human tenascin-C N-terminal cleavages occur just before and/or after the heptad repeats involved in subunit oligomerization. In the human protein, an additional cleavage site is identified in the alternative fibronectin type III repeat, and a unique cleavage by meprinbeta is located to the 7th constant fibronectin type III repeat in both chicken and human tenascin-C, cleavage at this site removes the C-terminal domain involved in its anti-adhesive activity

malfunction
-
N-terminal amyloid precursor protein fragments of about 11 and 20 kDa are not found in brain lysates of meprin beta -/- mice
malfunction
enzyme downregulation causes impaired intestinal mucin release and barrier function, and decreases tensile strength in the skin, but it also leads to protection against sepsis and renal injury. Enzyme upregulation can cause fibrosis, pulmonary hypertension, the Kawasaki syndrome, inflammatory bowel disease, and is involved in nephritis, cancer, and Alzheimer's disease, overview
malfunction
enzyme-deficient mice show lower amounts of mature collagen I compared with wild-type mice and exhibit significantly reduced collagen deposition in skin, along with markedly decreased tissue tensile strength
malfunction
meprin beta is the highest up-regulated gene in the lungs of Fosl2 transgenic mice compared to wild-type animals. Meprin beta knock-out mice exhibit decreased collagen deposition in skin resulting in impaired tensile strength, overview. Overexpression of meprin metalloproteases occurs under fibrotic conditions in the skin (keloids) and the lung (pulmonary hypertension)
malfunction
meprin beta-deficient mice, but not meprin alpha-deficient mice, subjected to cisplatin nephrotoxicity, significantly suppress excretion of cleaved nidogen-1
malfunction
meprin beta-knockout mice exhibit a reduced activation of the pro-inflammatory interleukin-18 and are therefore less susceptible to intestinal inflammation compared with wild-type mice. Mice lacking meprin alpha and meprin beta are significantly protected against renal ischaemia/reperfusion injury and bladder inflammation. Meprin beta-deficient mice show lower levels of the inflammatory marker interleukin-6 and decreased leucocyte infiltration after renal injury

malfunction
ablation of one of the two zinc metalloproteinases, meprin beta and BMP-1, leads to different collagen I associated phenotypes in vivo
malfunction
absence of N-APP fragments and increased endogenous sAPPalpha levels in the brains of meprin beta knockout mice
malfunction
knockout of meprin beta leads to increased sAPPalpha secretion in cortical neurons. BACE-1 activity is not increased by meprin beta preincubation. Decrease of Abeta2-40 and increase of mature APP in primary neurons of meprin beta knockout mice
malfunction
meprins KO mice exhibit deficiency in cell extravasation. Lack of meprins does not result in improved lung function in bleomycin treated mice. Decreased collagen deposition in meprin beta KO mice is concomitant with lower tissue density in comparison to wild-type mice. Expression of collagen I and III is elevated upon bleomycin in comparison to saline, but no differences are observed between different genotypes, indicating that post-translational modification is responsible for the reduction in collagen content in meprin beta KO mice
malfunction
the change to an arginine residue at position 32 represents an additional activation site used by furin-like proteases in the Golgi, which consequently leads to reduced shedding by ADAM17. The meprin beta G32R variant assesses cell proliferation, invasion through a collagen IV matrix, and outgrowth from tumor spheroids. Increased meprin beta G32R activity at the cell surface reduces cell proliferation, but increases cell invasion. The G32R meprin beta variant shows increased activity
malfunction
the protective A673T mutation in amyloid precursor protein (APP) results in reduced Abeta levels in patients, also prevents from meprin beta cleavage at position p2. Alterations of the amino acid composition close to the beta-secretase cleavage site may inhibit meprin beta activity on the generation of N-terminal truncated Abeta peptides

metabolism
BACE-1 acts as the major beta-secretase in vivo generating most of the amyloid beta (Abeta) peptides at position 1, while meprin beta may act as an alternative enzyme responsible for the release of small amounts of N-terminally truncated Abeta species. APP and meprin beta co-localize in the late secretory pathway or at the cell membrane. The aggregation of N-terminally truncated Abeta2-40 peptide is significantly different from that of the non-truncated wt Abeta1-40 peptide.

important beta-site cleaving enzyme 1 (BACE-1)-independent contribution of the metalloprotease meprin beta within the amyloidogenic pathway. The anti-amyloidogenic alpha-secretase a disintegrin and metalloproteinase domain-containing protein 10 (ADAM10) is a direct competitor for APP at the cell surface, but also a sheddase of inactive pro-meprin beta. The activity of meprin beta is strictly extracellularly regulated within the protease web. Meprin beta itself is identified as an inducer of ADAM10 activity
metabolism
meprin metalloproteases play a role in the pathology of ischemia/reperfusion- (IR-) induced renal injury. The endoplasmic reticulum-associated protein, osteosarcoma-9 (OS-9), interacts with the C-terminal tail of meprin beta (two-hybrid system). OS-9 also interacts with the hypoxia inducible factor-1alpha (HIF-1alpha) and the prolyl-hydroxylase, proteins which mediate the cell's response to hypoxia.

-
meprins stimulate epithelial Na+ channel (ENaC) expressed exogenously in Xenopus oocytes and endogenously in epithelial cells. Co-expression of ENaC subunits and meprin beta or alpha/beta in Xenopus oocytes increases amiloride-sensitive Na+ currents 2fold. The meprin-mediated increase in ENaC currents in oocytes and epithelial cell monolayers requires meprin beta, but not the alpha subunit
physiological function
basement membrane protein nidogen-1 is a target of meprin beta in cisplatin nephrotoxicity
physiological function
meprin beta acts as a sheddase at the cell surface where it releases the entire ectodomain of amyloid precursor protein, this cleavage event at the so-called beta-site enables gamma-secretase to further cleave the remaining C-terminal fragment of APP within the membrane, thereby releasing amyloid beta-peptides, which are known to be involved in the onset and progression of Alzheimer's disease. The enzyme is involved in inflammation by the release and maturation of cytokines and proteoglycans, it induces extracellular matrix assembly and fibrosis, and enhances cancer progression through transactivation of epidermal growth factor receptors. The cleavage of fibrillar procollagen by the enzyme is required and sufficient to induce collagen fibril assembly

meprin beta metalloproteinase is an important enzyme in extracellular matrix turnover, inflammation, and neurodegeneration in humans
physiological function
meprin-beta regulates production of pro-inflammatory factors via a disintegrin and metalloproteinase-10 (ADAM-10) dependent pathway in macrophages. Meprin-beta increases the production of pro-inflammatory cytokines, including interleukin-1beta, interleukin-18 and interleukin-6 in macrophages, but shows no effects on the level of ligands of epidermal growth factor receptor and its activation. Activation of NF-kappaB by meprin-beta is mediated by inhibiting ADAM10-downstream extracellular signal regulated kinase (ERK1/2) pathway, molecular mechanism, overview. Meprin-beta significantly induces the phosphorylation of ERK1/2 and its upstream MEK1/2
physiological function

physiological function
physiological relevance of the unique ability of meprin alpha, EC 3.4.24.18, and meprin beta to remove the both the C- and N-propeptides of type I procollagen, subsequently releasing fibril-forming mature collagen molecules. The enzyme contributes to the integrity of connective tissue in skin
physiological function
processing of the amyloid precursor protein is of critical importance, the enzyme cleaves amyloid precursor protein and liberates soluble N-terminal amyloid precursor protein fragments
physiological function
procollagen III is processed to its mature form by meprin alpha and meprin beta, an essential step in collagen fibril assembly. The metalloprotease meprin beta is involved in inflammation, neurodegeneration, cancer and fibrosis, overview. The enzyme mediates intestinal leucocyte infiltration, in accordance with its ability to cleave adhesion molecules and components of the extracellular matrix. Meprin beta induces cell death in terminally differentiated keratinocytes. Increased meprin activity at the basement membrane leads to degradation of the renal tubular laminin-nidogen complex and other components of the basement membrane, and to the cleavage of cell-adhesion molecules (E-cadherin and tenascin-C), consequently injuring the tubular basement membrane and leading to leucocyte infiltration

the metalloproteases meprin alpha and meprin beta are involved in inflammation, neurodegeneration, cancer and fibrosis, overview
physiological function
a reduction in activity is reported under increasing calcium concentrations for meprin beta
physiological function
actinonin, a meprin alpha (EC 3.4.24.18) and meprin beta inhibitor, does not inhibit the Reelin-cleaving activity of cerebellar granular neurons (CGN) and the amount of Reelin fragments in brains of meprin beta knock-out mice is not significantly different from that of the wild-type, indicating that meprin beta does not play a major role in Reelin cleavage under basal conditions. Meprin alpha and meprin beta probably join the modulators of Reelin signalling as they cleave Reelin at a specific site and are upregulated under specific pathological conditions
physiological function
meprin B cleaves kidney OS-9 in ischemia/reperfusion
physiological function
-
meprin beta acts at the cell surface as a sheddase, cleaving transmembrane proteins, such as the amyloid precursor protein (APP). Meprins cleave compounds of the extracellular matrix such as laminin-V, collagen IV, fibronectin or nidogen 1, but also growth factors, cytokines and peptide hormones, including bradykinin, angiotensins, and gastrin
physiological function
meprin beta contributes to collagen deposition in lung fibrosis and can also facilitate collagen maturation. They have been shown to cleave cell-cell contact molecules on epithelial cells such as E-cadherin and occludin. Meprin beta is positively regulated by TGF-beta1 in epithelial cells. Meprins are important for epithelial monolayer integrity, but meprins do not influence number and composition of inflammatory cells in the bleomycin treated lungs
physiological function
meprin beta is a membrane-bound metalloprotease involved in extracellular matrix assembly and inflammatory processes in health and disease. A disintegrin and metalloproteinase (ADAM)10 and ADAM17 are physiologically relevant sheddases of inactive promeprin beta, which influences its substrate repertoire and subsequent biologic functions. Specific N-terminal processing of ADAM9, 10, and 17 by meprin beta. Because ADAM prodomains can act as specific inhibitors, meprin beta plays a role in the regulation of ADAM activities. Prodomain cleavage by meprin beta causes increased ADAM protease activities, e.g. demonstrated by increased ectodomain shedding activity. As demonstrated by a bacterial activator of meprin beta and additional measurement of TNF-alpha shedding on bone marrow-derived macrophages, meprin beta/ADAM protease interactions likely influence inflammatory conditions

Meprin beta stimulates ADAM17 activity in macrophages because ADAM17-mediated TNF-alpha shedding is diminished in the absence of meprin beta
physiological function
meprin beta is potentially involved in disorders such as fibrosis and Alzheimer's disease
physiological function
metalloprotease meprin beta cleaves the Alzheimer's disease (AD) relevant amyloid precursor protein (APP) as a beta-secretase reminiscent of BACE-1, but predominantly generating N-terminally truncated Abeta2-x variants. Generation of aggregation prone N-terminally truncated amyloid beta peptides by meprin beta depends on the sequence specificity at the cleavage site. The N-terminally truncated Abeta2-40 variant shows increased aggregation propensity compared to Abeta1-40 and acts even as a seed for Abeta1-40 aggregation. Meprin beta cleavage of APP occurs prior to the endocytic compartments, as diminished APP endocytosis has no influence on meprin beta mediated Abeta generation. Mechanism, overview. Cellular interaction between meprin beta and APP occurs prior to endocytosis. The C-terminal motif NPxY (APPDELTANPxY) of APP is critical for proper endocytosis. Meprin beta generated Abeta2-40 promotes and seeds aggregation of Abeta peptides
physiological function
neurotoxic amyloid-beta (Abeta) plaques are one of the pathological hallmarks in Alzheimer disease patient brains. Abeta accumulates in the brain upon sequential, proteolytic processing of the amyloid precursor protein (APP) by beta- and gamma-secretases. The metalloproteinase meprin beta acts as an alternative beta-secretase, besides BACE-1, capable of generating truncated Abeta2-x peptides. Regulation of the alternative beta-secretase meprin beta by ADAM-mediated shedding. In the small intestine, meprin beta is essential for the detachment of the mucus by cleaving mucine 2 (MUC2). This is crucial for the functionality of the mucus barrier to impede bacterial overgrowth and infection. Meprin beta is an alternative beta-secretase within the complex protease web, regulating APP processing in health and disease, overview. Shed meprin beta does not act as sheddase

In the small intestine, meprin beta is essential for the detachment of the mucus by cleaving mucine 2 (MUC2). This is crucial for the functionality of the mucus barrier to impede bacterial overgrowth and infection. Meprin beta co-fractionates with APP and PS1 in the same high molecular weight fraction in wild-type mouse brains, and this fraction is responsible for the majority of Abeta generation
physiological function
protease meprin beta is expressed as an inactive zymogen and requires proteolytic maturation by tryptic serine proteases. Maturation of full-length meprin beta is required for its activity as a cell surface sheddase, releasing the ectodomains of transmembrane proteins, e.g. amyloid precursor protein (APP)
physiological function
the precursor protein APP is cleaved by meprin beta in distinct ways, either at the beta-secretase site resulting in increased levels of amyloid beta (Abeta) peptides, or at the N-terminus releasing 11 kDa, and 20 kDa peptide fragments. The latter event is discussed to be rather neuroprotective, whereas the ectodomain shedding of APP by meprin beta reminiscent to BACE-1 is in line with the amyloid hypothesis of Alzheimer's disease, promoting neurodegeneration. The N-terminal 11 kDa and 20 kDa peptide fragments represent physiological cleavage products, since they are found in human brains under different diseased or non-diseased states, whereas the fragments are completely missing in brains of meprin bata knock-out animals. Meprin beta generates N-APP fragments that have neither negative nor positive influence on neuronal cell viability

proteolytic modification
the recombinant N-terminally His-tagged human meprin beta zymogen is activated by cleavage with trypsin
proteolytic modification
zymogen promeprin beta is activated to mature meprin beta by proteolysis of the N-terminal prodomain, which is catalyzed by trypsin in the intestinal lumen and kallikrein-related peptidases (KLK-4, -5, and -8) in other tissues, overview
proteolytic modification
-
activation of meprin beta by proteolytic cleavage. Meprin beta contains a conserved sequence motif, which gives rise to enzymatic activation by tryptic serine proteases. Pancreatic trypsin performs this activation in the gut. Meprin beta cannot be activated by plasmin in the gut. In skin, the human tissue kallikrein-related peptidase 4 (KLK4), KLK5, and KLK8, cleave off the propeptide of meprin beta
proteolytic modification
matriptase-2 (MT-2), a type 2 transmembrane protein, fully activates meprin beta at the cell surface
proteolytic modification
metalloprotease meprin beta is activated by transmembrane serine protease matriptase-2 (MT2) at the cell surface. No processing by TMPRSS4 or pancreatic trypsin. The cleavage site for maturation within the propeptide of meprin beta is in close proximity to the plasma membrane, crystal structure analysis, PDB ID 4GWM. Proteomic identification of the MT2-dependent cleavage in pro-meprin beta by mass spectrometry
proteolytic modification
pro-meprin beta is activated by trypsin (15:1 w/w) at room temperature in the presence of 10 mM CaCl2 for 10 min. Subsequently, trypsin is inactivated by the addition of 5 mM 4-(2-aminoethyl)benzenesulfonyl fluoride (AEBSF)
proteolytic modification
proteolytic activation and shedding of meprin beta are mutually exclusive events. Cleavage of the pro-peptide completely blocks shedding of meprin beta by ADAM10 and ADAM17. The anti-amyloidogenic alpha-secretase a disintegrin and metalloproteinase domain-containing protein 10 (ADAM10) is a direct competitor for APP at the cell surface, but also a sheddase of inactive pro-meprin beta. Shedding of meprin beta by ADAM10/17 is completely abolished upon its activation by matrilysin-2 (MT-2, 3.4.24.23) at the cell surface. Only the proform of meprin beta can be shed. Meprin beta requires activation by tryptic proteases
proteolytic modification
proteolytic activation of pro-meprin beta at the cell surface, serine protease matriptase-2 (MT-2) is a membrane-bound activator of meprin beta. Shedding of meprin beta is mediated by endogenous ADAM10 or ADAM17. Shedding of meprin beta mutant G32R mediated by ADAM17 is impaired
proteolytic modification
the crystal structure of the zymogen form of meprin beta revealsthat the active side is shielded by the pro-peptide. Gln62 is directed away from the salt bridge that is formed by Glu163 and Lys248. The new N-terminus is formed by Asp62 after removal of the pro-peptide by tryptic serine protease cleavage between Arg61 and Gln62. In active meprin beta N62 forms a salt bridge with E163 and thus removes the new N-terminus from the active site, overview

the mutation is localized in the pro-peptide of the protease, the mutant is transported to the cell surface and exhibit expression comparable with wild-type meprin beta
G32R
naturally occuring mutant, the mutation is localized in the pro-peptide of the protease and identified in endometrium cancer, the mutant is transported to the cell surface and exhibit expression comparable with wild-type meprin beta, the mutant is more active against a peptide substrate (meprin beta-specific peptide substrate that is linked to a fluorogenic group (MCA) at the N-terminus and a quencher (DPN) at the C-terminus) and the interleukin-6 receptor than wild-type meprin beta. The change to an arginine residue at position 32 represents an additional activation site used by furin-like proteases in the Golgi, which consequently leads to reduced shedding by ADAM17. The meprin beta G32R variant assesses cell proliferation, invasion through a collagen IV matrix, and outgrowth from tumor spheroids. Increased meprin beta G32R activity at the cell surface reduces cell proliferation, but increases cell invasion. The G32R meprin beta variant shows increased activity. Phenotype, overview

COMMENTARY
LITERATURE
drug development
the astacin protease meprin beta is an emerging drug target for treatment of disorders such as kidney failure, fibrosis or inflammatory bowel disease
medicine
-
results suggest that meprinbeta may play a protective role against the progression of renal injury through the degradation of extracellular matrix and bioactive peptides
pharmacology
pharmacology
meprin-beta is strong candidate for a proinflammatory target
pharmacology
regulation of meprin activity by specific inhibition to reduce collagen maturation might be a suitable approach for the treatment of certain pathological conditions
