Steap3 Gene Summary [Mouse]
Enables cupric reductase (NADH) activity and ferric-chelate reductase (NADPH) activity. Acts upstream of or within exosomal secretion; positive regulation of intrinsic apoptotic signaling pathway in response to DNA damage by p53 class mediator; and transition metal ion transport. Located in endosome membrane and plasma membrane. Is expressed in several structures, including bone; genitourinary system; liver; nervous system; and white fat. Orthologous to human STEAP3 (STEAP3 metalloreductase). [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 mouse Steap3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
