Bak1 Gene Summary [Rat]
Enables several functions, including heat shock protein binding activity; identical protein binding activity; and protein-folding chaperone binding activity. Involved in several processes, including positive regulation of release of cytochrome c from mitochondria; release of cytochrome c from mitochondria; and response to hydrogen peroxide. Located in cytoplasm. Biomarker of intermittent claudication. 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]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Bak1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
