It is thought to play and important role in normal prostate and in prostate cancer progression as it showed increased expression in androgen-independent prostate cancer xenograftsSynonyms: IPCA-1, IPCA1, Metalloreductase STEAP2, PCANAP1, PUMPCn, Prostate cancer-associated protein 1, Protein upregulated in metastatic prostate cancer, STEAP-2, STMP, Six-transmembrane epithelial antigen of prostate 2, SixTransMembrane protein of prostate 1
