STEA3 Antibody detects endogenous levels of STEA3. STEAP3 a multi-pass membrane protein induced directly by p53. Plays an important role in facilitating exosome secretion. Enhances secretion in the DNA damage-induced p53-dependent exosomal secretory pathway. Localizes to vesicular-like structures at the plasma membrane and around the nucleus. Highly expressed in hematopoietic tissues where it localizes to the specialized endosome. An endosomal ferrireductase required for efficient transferrin-dependent iron uptake in erythroid cells. Participates in erythroid iron homeostasis by reducing Fe (3+) to Fe (2+). Can also reduce of Cu (2+) to Cu (1+), suggesting that it participates in copper homeostasis. Uses NAD (+) as acceptor.
