Target Background

Endosomal ferrireductase required for efficient transferrin-dependent iron uptake in erythroid cells. Participates in erythroid iron homeostasis by reducing Fe(3+) to Fe(2+). Can also reduce of Cu(2+) to Cu(1+), suggesting that it participates in copper homeostasis. Uses NADP(+) as acceptor. May play a role downstream of p53/TP53 to interface apoptosis and cell cycle progression. Indirectly involved in exosome secretion by facilitating the secretion of proteins such as TCTP.
Gene References into Functions
  1. In hepatocellular carcinoma (HCC), lower expression of the STEAP3 copper reductase and heavy Cu isotope enrichment have been reported for the tumor mass, relative to the surrounding tissue PMID: 28303916
  2. TSAP6 over expression is associated with poor survival in metastatic high-grade serous carcinoma. PMID: 27825812
  3. heterozygous STEAP3 mutations are relatively common in humans and that their deleterious effect in humans remains to be confirmed PMID: 26675350
  4. TSAP6 is a target of rhomboid protease RHBDD1-induced proteolysis. PMID: 22624035
  5. findings indicate that STEAP3 maintains iron storage in human malignant cells and tumor proliferation under the hypoferric condition PMID: 21871451
  6. TSAP6 may augment Myt1 activity and act downstream to p53 to interface apoptosis and cell-cycle progression PMID: 12606722
  7. role for TSAP6 in the export of TCTP and indicate that this multipass membrane protein could have a general role in the regulation of vesicular trafficking and secretion. PMID: 15319436
  8. The crystal structure of the human Steap3 oxidoreductase domain in the absence and presence of NADPH was determined. PMID: 18495927
  9. Down-regulated expression of the TSAP6 protein in liver is associated with a transition from cirrhosis to hepatocellular carcinoma PMID: 19236508
