STEAP4 - STEAP4 metalloreductase Gene
Also Known as TIARP; STAMP2; SchLAH; TNFAIP9
Species: Homo sapiens
About STEAP4
This gene has 3 transcripts (splice variants), 256 orthologues and 4 paralogues. Broad expression in fat (RPKM 50.0), prostate (RPKM 32.8) and 17 other tissues.
Summary
The protein encoded by this gene belongs to the STEAP (six transmembrane epithelial antigen of prostate) family, and resides in the golgi apparatus. It functions as a metalloreductase that has the ability to reduce both Fe(3+) to Fe(2+) and Cu(2+) to Cu(1+), using NAD(+) as acceptor. Studies in mice and human suggest that this gene maybe involved in adipocyte development and metabolism, and may contribute to the normal biology of the prostate cell, as well as prostate Cancer progression. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2011]
