Hmox1 Gene Summary [Rat]

Enables several functions, including heme binding activity; oxidoreductase activity, acting on paired donors, with incorporation or reduction of molecular oxygen, reduced flavin or flavoprotein as one donor, and incorporation of one atom of oxygen; and phospholipase D activity. Involved in several processes, including intracellular signal transduction; negative regulation of apoptotic process; and regulation of gene expression. Located in caveola; endoplasmic reticulum; and nucleus. Used to study several diseases, including artery disease (multiple); cerebrovascular disease (multiple); hepatic vascular disease (multiple); limb ischemia; and sciatic neuropathy. Biomarker of several diseases, including Sjogren's syndrome; artery disease (multiple); brain disease (multiple); liver disease (multiple); and lung disease (multiple). Human ortholog(s) of this gene implicated in several diseases, including artery disease (multiple); cerebrovascular disease (multiple); factor VIII deficiency; lung disease (multiple); and type 2 diabetes mellitus. Orthologous to human HMOX1 (heme oxygenase 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 Hmox1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
