Epas1 Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
EPAS1 (Endothelial PAS Domain Protein 1), also known as HIF-2α (Hypoxia-Induble Factor 2 alpha), is a transcription factor that plays a critical role in cellular responses to hypoxia. It regulates genes involved in oxygen homeostasis, angiogenesis, erythropoiesis, and metabolic adaptation.
