Cyba Gene Summary [Rat]

Contributes to superoxide-generating NAD(P)H oxidase activity. Involved in several processes, including cellular response to L-glutamine; cellular response to gamma radiation; and positive regulation of cell population proliferation. Located in several cellular components, including focal adhesion; perinuclear endoplasmic reticulum; and stress fiber. Part of NADPH oxidase complex. Used to study hypertension and pulmonary hypertension. Biomarker of diabetic retinopathy; end stage renal disease; hypertension; and myocardial infarction. Human ortholog(s) of this gene implicated in artery disease (multiple); asthma; chronic obstructive pulmonary disease; and phagocyte bactericidal dysfunction (multiple). Orthologous to human CYBA (cytochrome b-245 alpha chain). [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 Cyba often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
