EPAS1 (HIF-2α)
EPAS1, also known as HIF-2α, is a protein that helps the body respond to low oxygen levels, such as at high altitudes or during certain medical conditions. It is part of the hypoxia-inducible factor (HIF) family, which activates genes that increase oxygen delivery and adaptation. HIF-2α is primarily involved in controlling red blood cell production and blood vessel growth. When oxygen is scarce, it becomes more active, triggering these responses. Proper regulation of EPAS1 is important for maintaining oxygen balance and overall health.
