Summary: Enables calcium-dependent cysteine-type endopeptidase activity. Involved in cellular response to amino acid stimulus and proteolysis. Acts upstream of or within blastocyst development and myoblast fusion. Located in several cellular components, including chromatin; cytosol; and lysosome. Is expressed in several structures, including hindbrain; lens epithelium; oral region epithelium; skin; and spinal cord floor plate. Orthologous to human CAPN2 (calpain 2).

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.
