COMMENTARY 
LITERATURE
malfunction
metabolism
calpain 3 has a central role in the regulation of the important cell fate-governing nuclear factor-kappaB pathway. Calpain 3-mediated cardiac ankyrin repeat protein cleavage strengthens its interaction with titin N2A
physiological function
malfunction
-
deficiency in calpain 3 is associated with apoptosis as indicated by increases of caspase 3 activity, the absence of calpain 3 modifies the sarcoplasmic reticulum Ca2+ release, by a decrease of the sarcoplasmic reticulum content, an impairment of ryanodine receptor signalling, and an increase of L-type Ca2+ channel activity
malfunction
-
inactivating mutations of the CAPN3 gene, encoding the muscle-specific calpain-3, result in the limb-girdle muscular dystrophy-2A
malfunction
-
loss of CAPN3 is 100% specific for limb-girdle muscular dystrophy 2A
malfunction
-
mitochondrial abnormalities, energy deficit and oxidative stress are features of calpain 3 deficiency in skeletal muscle
malfunction
mutations in calpain 3 underlie limb-girdle muscular dystrophy 2A
malfunction
mutations in calpain 3 underlie limb-girdle muscular dystrophy 2A
malfunction
gene mutations causing CAPN3 defects are responsible for limb-girdle muscular dystrophy type 2A (LGMD2A)
malfunction
limb-girdle muscular dystrophy type 2a arises from mutations in the Ca+-activated intracellular cysteine protease calpain-3
malfunction
loss of calpain-3 (CAPN3) activity leads to limb-girdle muscular dystrophy 2A. Calpain-3 mediates regulation of the Na+-Ca2+ exchanger isoform 3. The loss of regulation of Na+-Ca2+ exchanger isoform 3 (NCX3) by calpain-3 can be implicated in diverse muscular pathologies such as the limb-girdle muscular dystrophy 2A
physiological function
-
calcium-dependent plasma membrane repair does not require calpain-3
physiological function
-
calpain 3 is involved in the myogenic differentiation process, calpain 3 participates in the establishment of the pool of reserve cells by decreasing the transcriptional activity of the key myogenic regulator MyoD via proteolysis independently of the ubiquitin-proteasome degradation pathway
physiological function
-
calpain 3 variants can play a proapoptotic role in melanoma cells and its downregulation, as observed in highly aggressive lesions, can contribute to melanoma progression
physiological function
-
calpain 3-dependent proteolysis plays a role in activating support proteins of intracellular Ca2+ signalling at a stage of cellular differentiation which is crucial for skeletal muscle regeneration
physiological function
-
the enzyme plays a role in tenderizing connective tissue networks during growth and moulting
physiological function
aberrant calpain 3 splicing contributes to the muscle differentiation defects of facioscapulohumeral muscular dystrophy patients
physiological function
proteolytic processing of C-terminal titin by calpain 3 has an important role in normal muscle
physiological function
proteolytic processing of C-terminal titin by calpain 3 has an important role in normal muscle
physiological function
calpain-3 down-regulation can be regarded as a mechanism contributing to melanoma progression. Overexpression of the calpain-3 splicing variant hMp84 in A375 cells or HT-144 cells causes inhibition of cell proliferation, cell death, and increase of both ROS levels and F2-isoprostanes
