MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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 a member of the calpain large subunit family. [provided by RefSeq, Jun 2012]

Protein Function and Prediction

Capn12 encodes CAPN12, a member of the calpain large subunit family of cytosolic calcium-activated cysteine proteases (1).  Calpains function in several cellular processes including cell division, integrin-cytoskeletal interactions, synaptic plasticity, and apoptosis. CAPN12 has potential protease and calcium-binding domains, similar to the classical calpains (1).  The function of CAPN12 has not been elucidated, but expression in the hair follicle indicate it may function to regulate hair growth.


In situ hybridization and Northern blot analyses determined that the cortex of the hair follicle is the major site of Capn12 expression during the anagen phase of the hair cycle (1)
