Summary: Enables calcium-dependent cysteine-type endopeptidase inhibitor activity and protease binding activity. Involved in several processes, including animal organ regeneration; myoblast fusion; and skeletal muscle atrophy. Located in membrane and postsynaptic density. Used to study brain ischemia. Biomarker of alcohol use disorder; hypertension; and muscular atrophy. Human ortholog(s) of this gene implicated in PLACK syndrome; Parkinson's disease; autoimmune disease (multiple); congenital myasthenic syndrome 1A; and vasculitis. Orthologous to human CAST (calpastatin). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
