clp-4 encodes a large calpain subunit that is homologous to Drosophila CalpainB and the mammalian muscle-specific Calpain 3 proteins (OMIM:114240, mutations are associated with limb-girdle muscular dystrophy); by homology, CLP-4 is predicted to function as a nonlysosomal, calcium-dependent, cysteine protease that is involved in intracellular proteolysis and peptidolysis; however, as loss of clp-4 activity via RNA-mediated interference (RNAi) does not result in any obvious abnormalities, the precise role of CLP-4 in C. elegans development and/or behavior is not yet known.
Predicted to enable calcium-dependent cysteine-type endopeptidase activity. Predicted to be involved in proteolysis. Predicted to be located in cytoplasm. Expressed in GABAergic neurons; body wall musculature; dorsal nerve cord; and ventral nerve cord. Human ortholog(s) of this gene implicated in Alzheimer's disease; autosomal dominant limb-girdle muscular dystrophy; autosomal recessive limb-girdle muscular dystrophy type 2A; hereditary spastic paraplegia 76; and stomach cancer. Is an ortholog of several human genes including CAPN1 (calpain 1); CAPN2 (calpain 2); and CAPN3 (calpain 3).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
