Por Gene Summary [Rat]

Enables several functions, including iron-cytochrome-c reductase activity; nucleotide binding activity; and oxidoreductase activity, acting on NAD(P)H, heme protein as acceptor. Involved in several processes, including cellular response to follicle-stimulating hormone stimulus; nitric oxide catabolic process; and oxoacid metabolic process. Predicted to be located in intracellular membrane-bounded organelle. Predicted to be active in cytosol. Human ortholog(s) of this gene implicated in Antley-Bixler syndrome with disordered steroidogenesis; congenital adrenal hyperplasia; and cytochrome P450 oxidoreductase deficiency. Orthologous to human POR (cytochrome p450 oxidoreductase). [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 Por often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
