Summary This gene encodes a transcription factor involved in the induction of genes regulated by oxygen, which is induced as oxygen levels fall. The encoded protein contains a basic-helix-loop-helix domain protein dimerization domain as well as a domain found in proteins in signal transduction pathways which respond to oxygen levels. Mutations in this gene are associated with erythrocytosis familial type 4. [provided by RefSeq, Nov 2009].

GeneRIFs: Gene References Into Functions What's a GeneRIF?

What is the normal function of the EPAS1 gene?

The EPAS1 gene, often known as HIF2A, provides instructions for making a protein called hypoxia-inducible factor 2-alpha (HIF-2α). This protein is one part (subunit) of a larger protein complex called HIF, which plays a critical role in the body's ability to adapt to changing oxygen levels. HIF controls several important genes involved in cell division, the formation of new blood vessels, and the production of red blood cells. It is the major regulator of a hormone called erythropoietin, which controls red blood cell production.

HIF-2α is constantly produced in the body. When adequate oxygen is available, other proteins target HIF-2α to be broken down (degraded) so it does not build up. However, when oxygen levels are lower than normal (hypoxia), HIF-2α is degraded at a slower rate. Consequently, more HIF is available to stimulate the formation of new blood vessels and the production of red blood cells. These activities help maximize the amount of oxygen that can be delivered to the body's organs and tissues.

Studies suggest that the EPAS1 gene is involved in the body's adaptation to high altitude. At higher altitudes, such as in mountainous regions, air pressure is lower and less oxygen enters the body through the lungs. Over time, the body compensates for the lower oxygen levels by changing breathing patterns and producing more red blood cells and blood vessels.
