Capn3

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 satellite cell activation involved in skeletal muscle regeneration; and regulation of DNA-templated transcription. Acts upstream of or within 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, Jul 2025]

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Capn3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
