Human HIF-2 alpha/EPAS1 Antibody

The hypoxia-inducible transcription factor 2 alpha (HIF-2 alpha) is stabilized in hypoxic tissue and, similarly to HIF-1 alpha, complexes with Aryl hydrocarbon receptor nuclear translocator (ARNT). Both the HIF-1 and HIF-2 complexes bind hypoxia-response elements (HREs) in the promoters of many genes involved in adapting to an environment of insufficient oxygen or hypoxia. HIF-1 and HIF-2 do not appear completely redundant, although specific functions are only beginning to be elucidated. Hypoxic tissue environments occur in vascular and pulmonary diseases as well as cancer, which illustrates the potentially broad impact of gene regulation by both HIF-1 alpha and HIF-2 alpha.
