Summary: Enables identical protein binding activity. Involved in cellular response to UV; positive regulation of apoptotic process; and release of cytochrome c from mitochondria. Acts upstream of or within several processes, including apoptotic process involved in blood vessel morphogenesis; apoptotic signaling pathway; and lymphocyte apoptotic process. Located in cytosol; endoplasmic reticulum; and mitochondrial outer membrane. Part of BAK complex. Is expressed in several structures, including alimentary system; brain; branchial arch; genitourinary system; and hemolymphoid system gland. Human ortholog(s) of this gene implicated in ataxia telangiectasia and cervix carcinoma. Orthologous to human BAK1 (BCL2 antagonist/killer 1). [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.
