HIF-2

HIF-2 (Hypoxia-Inducible Factor 2) is a protein that helps the body respond to low oxygen levels, or hypoxia. When oxygen is scarce, HIF-2 activates genes that promote new blood vessel growth and oxygen delivery, ensuring tissues receive enough oxygen to function. It plays a vital role in adapting to environments like high altitudes and is involved in certain health conditions, including some cancers. Essentially, HIF-2 acts as a molecular sensor and regulator, helping the body adjust to oxygen deprivation by triggering appropriate biological responses.
