Previous GeneCards Identifiers for CAPN1 Gene
The calpains, calcium-activated neutral proteases, are nonlysosomal, intracellular cysteine proteases. The mammalian calpains include ubiquitous, stomach-specific, and muscle-specific proteins. The ubiquitous enzymes consist of heterodimers with distinct large, catalytic subunits associated with a common small, regulatory subunit. This gene encodes the large subunit of the ubiquitous enzyme, calpain 1. Several transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Nov 2010]
GeneCards Summary for CAPN1 Gene
CAPN1 (Calpain 1) is a Protein Coding gene. Among its related pathways are Degradation of the extracellular matrix and Alzheimers Disease Pathway. GO annotations related to this gene include calcium ion binding and calcium-dependent cysteine-type endopeptidase activity. An important paralog of this gene is CAPN9.
UniProtKB/Swiss-Prot for CAPN1 Gene
Calcium-regulated non-lysosomal thiol-protease which catalyze limited proteolysis of substrates involved in cytoskeletal remodeling and signal transduction.
Calpains are a group of calcium-sensitive cysteine proteases that are ubiquitously expressed in mammals. Structurally, calpains contain two subunits; an 80 kDa catalytic subunit and a 28 kDa regulatory subunit that functions as a chaperone to stabilize the 80 kDa structure.
