Summaries for HPX Gene

Entrez Gene Summary for HPX Gene

  • This gene encodes a plasma glycoprotein that binds heme with high affinity. The encoded protein is an acute phase protein that transports heme from the plasma to the liver and may be involved in protecting cells from oxidative stress. [provided by RefSeq, Apr 2009]

GeneCards Summary for HPX Gene

HPX (Hemopexin) is a Protein Coding gene. Diseases associated with HPX include Pseudotumor Cerebri and Blackwater Fever. Among its related pathways are Binding and Uptake of Ligands by Scavenger Receptors and Vesicle-mediated transport. GO annotations related to this gene include heme transporter activity.

UniProtKB/Swiss-Prot for HPX Gene

  • Binds heme and transports it to the liver for breakdown and iron recovery, after which the free hemopexin returns to the circulation.
