Steap4 Gene Summary [Rat]
Predicted to enable several functions, including FAD binding activity; heme binding activity; and oxidoreductase activity, acting on metal ions, NAD or NADP as acceptor. Predicted to be involved in copper ion import; fat cell differentiation; and protein homotrimerization. Predicted to act upstream of or within iron import into cell. Predicted to be located in membrane and nucleoplasm. Predicted to be active in endosome and plasma membrane. Orthologous to human STEAP4 (STEAP4 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 Steap4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
