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).
