Summary: Enables protein heterodimerization activity. Acts upstream of or within negative regulation of apoptotic process. Predicted to be located in endoplasmic reticulum membrane and nuclear membrane. Predicted to be active in mitochondrial outer membrane. Is expressed in several structures, including anterior lateral mesoderm; corpuscles of Stannius; digestive system; nervous system; and pleuroperitoneal region. Human ortholog(s) of this gene implicated in several diseases, including Alzheimer's disease; carcinoma (multiple); hematologic cancer (multiple); intracranial aneurysm; and prostate cancer. Orthologous to human BCL2 (BCL2 apoptosis regulator). [provided by Alliance of Genome Resources, Jul 2025]

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.
