Bax Gene Summary [Rat]
Enables BH domain binding activity; heat shock protein binding activity; and protein-folding chaperone binding activity. Involved in several processes, including mitochondrion organization; response to anesthetic; and response to ischemia. Located in several cellular components, including cytosol; mitochondrial outer membrane; and perinuclear region of cytoplasm. Used to study brain glioma; endometriosis; morphine dependence; and pre-malignant neoplasm. Biomarker of several diseases, including artery disease (multiple); brain disease (multiple); heart disease (multiple); lung disease (multiple); and neurodegenerative disease (multiple). Human ortholog(s) of this gene implicated in acute lymphoblastic leukemia; ataxia telangiectasia; colon adenocarcinoma; and colorectal cancer. Orthologous to human BAX (BCL2 associated X, apoptosis regulator). [provided by Alliance of Genome Resources, Apr 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 Bax often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
