Summaries for CAPN2 Gene

Entrez Gene Summary for CAPN2 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 2. Multiple heterogeneous transcriptional start sites in the 5' UTR have been reported. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2009]

GeneCards Summary for CAPN2 Gene

CAPN2 (Calpain 2, (M/II) Large Subunit) is a Protein Coding gene. Among its related pathways are ERK Signaling and Apoptosis Pathway. GO annotations related to this gene include calcium ion binding and cysteine-type peptidase activity. An important paralog of this gene is CAPN9.

UniProtKB/Swiss-Prot for CAPN2 Gene

  • Calcium-regulated non-lysosomal thiol-protease which catalyze limited proteolysis of substrates involved in cytoskeletal remodeling and signal transduction. Proteolytically cleaves MYOC at Arg-226 (PubMed:17650508).

Tocris Summary for CAPN2 Gene

  • Calpains are a group of calcium-sensitive cysteine proteases that are ubiquitously expressed in mammals. This family contains 14 members with mu-calpain (calpain 1) and m-calpain (calpain 2) being the most well-characterized. 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. Calpains are regulated by Ca2+ concentration, phosphorylation, calpastatin and probably by altering their subcellular localization (limiting access to substrate). These endopeptidases have numerous functions including, but not limited to, remodeling of cytoskeletal attachments to the plasma membrane during cell fusion and cell motility, proteolytic modification of molecules in signal transduction pathways, degradation of enzymes controlling progression through the cell cycle, regulation of gene expression, substrate degradation in some apoptotic pathways, and an involvement in long-term potentiation. Perturbations in calpain activity have been associated in pathophysiological processes contributing to type II diabetes (calpain 10), Alzheimer's disease (calpain 1), gastric cancer (calpain 9) and muscular dystrophy (calpain 3).
