Background: STEAP1

STEAP1 (six-transmembrane epithelial antigen of the prostate-1) is a 40 kDa protein (predicted) of the STEAP family of metalloreductases. It is expressed mainly at cell‑cell junctions between prostate secretory epithelium, and up‑regulated in prostate and some bladder, colon and ovarian cancers and Ewing’s sarcomas. Human STEAP1 is 339 amino acids (aa) in length. It contains a ferric oxidoreductase domain (aa 119‑265) that includes transmembrane sequences (# 2, 3, 4, and part of 5, out of 6 sequences). Two splice forms diverge at aa 255, terminating after aa 58 or 259. Over aa 1‑71, human and mouse STEAP1 share 68% aa identity.
