SYSTEMATIC NAME
IUBMB Comments
ATP:protein phosphotransferase (MAPKK-activated)
Phosphorylation of specific tyrosine and threonine residues in the activation loop of this enzyme by EC 2.7.12.2, mitogen-activated protein kinase kinase (MAPKK) is necessary for enzyme activation. Once activated, the enzyme phosphorylates target substrates on serine or threonine residues followed by a proline [6]. A distinguishing feature of all MAPKs is the conserved sequence Thr-Xaa-Tyr (TXY). Mitogen-activated protein kinase (MAPK) signal transduction pathways are among the most widespread mechanisms of cellular regulation. Mammalian MAPK pathways can be recruited by a wide variety of stimuli including hormones (e.g. insulin and growth hormone), mitogens (e.g. epidermal growth factor and platelet-derived growth factor), vasoactive peptides (e.g. angiotensin-II and endothelin), inflammatory cytokines of the tumour necrosis factor (TNF) family and environmental stresses such as osmotic shock, ionizing radiation and ischaemic injury.

malfunction
a kgb-1 null mutant, obtained by targeted deletion, shows extra germ cells, increased number of P granules, and temperature-sensitive sterility. RNAi-mediated knockdown of glh-1 in kgb-1 mutants partially rescues the P granule number and temperature-sensitive sterility. Null mutations in vhp-1 cause larval lethality, which can be suppressed by null mutations in mlk-1, mek-1, kgb-1, dlk-1, or pmk-3; null mutations in vhp-1 cause larval lethality, which can be suppressed by null mutations in mlk-1, mek-1, kgb-1, dlk-1, or pmk-3. DLK-1/PMK-3 are identified to affect cilia length, via regulation of RAB-5 endosomes; removing the 3'-UTR of pmk-2 causes its expression in the intestine, which is sufficient to rescue the Esp phenotype of pmk-1 mutants. The Esp mutant phenotype worms show enhanced susceptibility to Pseudomonas aeruginosa that causes an intestinal infection and eventual death of the worm

root elongation in seedlings of the loss-of-function mutants mpk6-2 and mpk6-3 is less sensitive to NaCl or Na-glutamate, but not to KCl or mannitol, as compared with that of wild-type seedlings. The tolerance of mpk6 to Na+ toxicity is Ca2+-dependent. At the plasma membrane, increased concentrations of NaCl increase the inward Na+-conducted currents while decreasing the outward Na+-conducted currents in wild-type root cells, attended by a positive shift in membrane potential. In mpk6 mutant root cells, NaCl significantly increases outward but not inward Na+-conducted currents, accompanied by a negative shift in membrane potential. Mutant mpk6 decreases NaCl-induced the Na+ accumulation by modifying PM Na+ flux in root cells. Mutant mpk6 accumulates less Na+ in response to NaCl because of the increased cytosolic Ca2+ level in root cells; thus, its root elongation is less inhibited than that of WT by NaCl

the enzyme knockout mutant shows colonies that are smaller and more compact thant the wild-type colonies. Additionally, while the wild-type produces abundant aerial hyphae on PDA plates, the mutant produces fewer and shorter aerial hyphae. Although mutation of the MAP kinase gene shows substantial effect on the fungal hyphal structure and colony morphology, the conidia produced by the mutant are similar to the wild-type with normal size and morphology. The mutant has reduced production of chitin and reduced expression levels of chitin biosynthetic genes. The mutant DELTAFoSlt2 shows lower chitin contents than wild-type and complemented strain DELTAFoSlt2-c. The mutant strain also shows reduced levels of different chitin syntases, overview. The mutant is sensitive to H2O2. The siderophore biosynthetic gene sidA is 2fold upregulated in mutant DELTAFoSlt2.

The DELTACshog1 mutant is able to infect barley roots, no significant difference in virulence is observed for DELTACshog1 mutants compared to the wild-type; the DELTACsfus3 knockout mutant is defective in conidiation and formation of appressoria-like structures, showing hypersensitivity to oxidative stress and loss of pathogenicity on non-wounded leaves of Hordeum vulgare cv. Bowman. When inoculated on wounded leaves of Bowman, the DELTACsfus3 knockout mutant is reduced in virulence compared to the wild-type. The DELTACsfus3 mutant fails to cause any symptoms on barley roots; the DELTACsslt2 knockout mutant produces more vegetative hyphae, has lighter pigmentation, are more sensitive to cell wall degrading enzymes, and are reduced in virulence on Bowman leaves compared to the wild-type, although they formed normal appressoria like the wild-type.

endoplasmic reticulum homeostasis is regulated by a network of signaling pathways which include stearoyl-CoA desaturase (SCD)-1, p38 mitogen-activated protein kinase (MAPK) and the unfolded protein response (UPR). All these pathways are located at the interface of cell cycle control and cell stress. Inhibition or silencing of SCD-1, via inhibitor CAY10566 or siRNA, specifically induces phosphorylation and activation of p38 MAPK. SCD-1 counteracts palmitate-induced endoplasmic reticulum stress by reducing p38 MAPK activation.

hepatocyte coculture induces the re-expression of E-cadherin via abrogation of autocrine EGFR signaling pathway in prostate cancer (PCa) cells and this confers a survival advantage. Hepatocytes educate PCa cells to undergo mesenchymal to epithelial reverting transition (MErT) by modulating the activity of p38 and ERK1/2. Hepatocytes inhibit p38 and ERK1/2 activity in prostate cancer cells, which allows E-cadherin re-expression. Introduction of constitutively active MEK6 and MEK1 to DU-145 cells cocultured with hepatocytes abrogates E-cadherin re-expression. At least a partial phenotypic reversion can be achieved by suppression of p38 and ERK1/2 activation in DU-145 cells even in the absence of hepatocytes

pathogen-associated molecular patterns (PAMPs) are recognized by plant pattern recognition receptors to activate PAMP-triggered immunity. PAMP perception enhances phosphorylation of BES1. BES1 is a unique direct substrate of MPK6 in PAMP-triggered immunity signaling. MAPK-mediated BES1 phosphorylation is another BES1 modulation mechanism in plant cell signaling, in addition to GSK3-like kinase-mediated BES1 phosphorylation and F box protein-mediated BES1 degradation. BES1 phosphorylation induced by flg22 occurs downstream of MAPK activation. MKK5K99M acts as a dominant negative mutant that partially blocks MAPK activation and downstream PTI signaling

the p38gamma C-terminus is an efficient inducer of cell death after its intracellular delivery. Binding of the C-terminal sequence of p38gamma to PTPN4 abolishes the catalytic autoinhibition of PTPN4 and thus activates the phosphatase, which can efficiently dephosphorylate the activation loop of p38gamma. The p38gamma-PTPN4 interaction promotes cellular signaling, preventing cell death induction
physiological function
activation of JNK signaling occurs under conditions of heavy metal stress. Olfactory memory in Caenorhabditis elegans allows for the association of cues with positive or negative experiences. The loss of these memories proceeds through the UNC-43/TIR-1/NSY-1/SEK-1/JNK-1 cascade; PMK-3 acts during neuronal development. vhp-1 regulates MAP kinases in axon regeneration. svh-1 and svh-2 likely provide a layer of specificity in controlling the KGB-1/JNK pathway, independently of PMK-3 in axon injury response, crosstalk between the KGB-1 and PMK-3 cascades. The avoidance of high CO2 environments and pathogens is mediated by MOM-4/MKK-4/PMK-3 in the BAG neuron; roles for KGB-2 are in excess carbon dioxide (hypercapnia)-induced fertility defects and a slight negative role in axon injury response; the enzyme is involved in P granule formation in germ cell proliferation. KGB-1 can bind and phosphorylate GLH-1, which leads to degradation of phosphorylated GLH-1. KGB-1 activity negatively regulates GLH-1 and the steady state level of P granules to maintain fertility. vhp-1 regulates MAP kinases in axon regeneration. svh-1 and svh-2 likely provide a layer of specificity in controlling the KGB-1/JNK pathway, independently of PMK-3 in axon injury response, crosstalk between the KGB-1 and PMK-3 cascades. The aversive reaction to microbial exposure is mediated by a MLK-1/MEK-1(SEK-1)/KGB-1 pathway; the NSY-1/SEK-1/PMK-1 and PMK-2 cascade acts during neuronal development to regulate AWC asymmetry. The activation of this cascade is regulated in part by calcium, via calmodulin kinase II, as well as the conserved protein TIR-1. PMK-1 and PMK-2 act redundantly downstream of TIR-1/NSY-1/SEK-1 to induce TPH-1 expression in the ADF neuron following exposure to bacteria.

MAPKs that are in different families (e.g. ERK, JNK, and p38) can bind selectively to D-sites in their authentic substrates and regulators while discriminating against D-sites in other pathways. The short hydrophobic region at the distal end of the D-site plays a critical role in determining the high selectivity of JNK MAPKs for docking sites in their cognate MAPK kinases. These specificity-determining differences are also found in the D-sites of the ETS family transcription factors Elk-1 and Net. Swapping two hydrophobic residues between these D-sites switches the relative efficiency of Elk-1 and Net as substrates for ERK versus JNK. Comparison of the hydrophobic submotif in strong versus weak JNK-binding D-sites, overview. The D-sites of the JNK pathway activator MKK4 contains LXL, as do all three of the D-sites in activator MKK7 in the first 3 residues of the hydrophobic submotif. MKK D-sites that bind JNK weakly lack an extended hydrophobic motif
