STEAP2 - STEAP2 metalloreductase Gene
Also Known as STMP; IPCA1; PUMPCn; STAMP1; PCANAP1
Species: Homo sapiens
About STEAP2
This gene has 10 transcripts (splice variants), 195 orthologues and 4 paralogues. Biased expression in prostate (RPKM 47.3), gall bladder (RPKM 4.2) and 6 other tissues.
Summary
This gene is a member of the STEAP family and encodes a multi-pass membrane protein that localizes to the Golgi complex, the plasma membrane, and the vesicular tubular structures in the cytosol. A highly similar protein in mouse has both ferrireductase and cupric reductase activity, and stimulates the cellular uptake of both iron and copper in vitro. Increased transcriptional expression of the human gene is associated with prostate Cancer progression. Alternate transcriptional splice variants, encoding different isoforms, have been characterized.
