Capn3 - calpain 3

Enables calcium-dependent cysteine-type endopeptidase activity; metal ion binding activity; and molecular adaptor activity. A structural constituent of muscle. Involved in several processes, including G1 to G0 transition involved in cell differentiation; positive regulation of release of sequestered calcium ion into cytosol; and regulation of transcription, DNA-templated. Acts upstream of or within negative regulation of skeletal muscle cell differentiation; proteolysis; and sarcomere organization. Located in cytosol and plasma membrane. Part of protein-containing complex. Is expressed in several structures, including brain; eye; heart; and musculature. Used to study autosomal recessive limb-girdle muscular dystrophy type 2A. Human ortholog(s) of this gene implicated in autosomal dominant limb-girdle muscular dystrophy; autosomal recessive limb-girdle muscular dystrophy type 2A; and muscular dystrophy. Orthologous to human CAPN3 (calpain 3). [provided by Alliance of Genome Resources, Apr 2022]
