Steap2 Gene Summary [Rat]
Predicted to enable cupric reductase (NADH) activity and ferric-chelate reductase (NADPH) activity. Predicted to be involved in several processes, including Golgi to plasma membrane transport; copper ion import; and regulated exocytosis. Predicted to act upstream of or within copper ion import across plasma membrane and iron ion import across plasma membrane. Predicted to be located in Golgi membrane; cytoplasmic vesicle; and cytosol. Predicted to be active in endosome and plasma membrane. Orthologous to human STEAP2 (STEAP2 metalloreductase).

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 Steap2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
