The Six-transmembrane epithelial antigen of prostate 2 (STEAP2) is a metalloreductase that belongs to the STEAP family. It is localized in secretory and endocytic pathway organelles. The STEAP2 gene is mapped to human chromosome 7q21.13.
Immunogen
a 16 amino acid peptide from near the carboxy-terminus of human STEAP2.
Biochem/physiol Actions
The Six-transmembrane epithelial antigen of prostate 2 (STEAP2) being localized in Golgi membrane and cytoplasmic vesicles, may have a critical role in the endocytic pathway. It is highly expressed in prostate carcinomas (PCa) and promotes tumor invasion and migration. Along with STEAP3 and 4, STEAP2 levels are implicated in favoring copper and iron uptake. Studies on targeted STEAP2 knockdown have reported a reduction in PCa progression.

To investigate the prognostic value of expression levels of the genes STEAP1 and STEAP2, and of STEAP1 protein, in prostate carcinomas (PCa). STEAP1 and STEAP2 transcript levels were evaluated by RT-qPCR in samples from 35 PCa, 24 adjacent non-neoplastic prostate
Six-transmembrane epithelial antigen of the prostate-2 (STEAP2) expression is increased in prostate cancer when compared to normal prostate, suggesting STEAP2 may drive prostate cancer progression. This study aimed to establish the functional role of STEAP2 in prostate tumourigenesis and evaluate
STEAP2 is a member of the Six-Transmembrane Epithelial Antigen of the Prostate (STEAP) protein family that is proposed to function as metalloreductase. While STEAP2 shows a complex subcellular distribution pattern localizing to both secretory and endocytic pathway organelles, how such
