Rabbit anti Human STEAP1 antibody recognizes STEAP1, also known as six transmembrane epithelial antigen of the prostate. STEAP1 is a ~39 kDa protein and member of a family of cell surface serpentine transmembrane antigens of the prostate.

STEAP1 is predominantly expressed in human prostate and is up-regulated in several cancer lines including prostate, ovarian, cervical, breast, testicular, bladder, colon and Ewing sarcoma. It is significantly expressed at cell-cell junctions and has been shown to be a target of human CD8 T cells. This indicates that it could be used as a potential target for cancer immunotherapy. This antibody does not cross-react with other STEAP-proteins.
