Summary: Enables cysteine-type endopeptidase activator activity involved in apoptotic process; cysteine-type endopeptidase activity; and identical protein binding activity. Involved in several processes, including muscle cell cellular homeostasis; negative regulation of cellular response to manganese ion; and positive regulation of apoptotic process. Located in several cellular components, including mitochondrion; neuronal cell body; and perinuclear region of cytoplasm. Part of caspase complex. Is expressed in several structures, including ABaraapapaa; NSM; apoptotic cell; germ line; and oocyte. Human ortholog(s) of this gene implicated in several diseases, including autoimmune lymphoproliferative syndrome type 2B; gastrointestinal system cancer (multiple); lung cancer (multiple); neurodegenerative disease (multiple); and ovarian carcinoma. Orthologous to several human genes including CASP2 (caspase 2) and CASP3 (caspase 3). [provided by Alliance of Genome Resources, May 2025]
