Biochem Physiol Actions: EPAS1 is a transcription factor involved in the induction of oxygen regulated genes. EPAS1 binds to core DNA sequence 5'-[AG]CGTG-3' within the hypoxia response element (HRE) of target gene promoters. EPAS1 regulates the vascular endothelial growth factor (VEGF) expression and seems to be implicated in the development of blood vessels and the tubular system of lung. EPAS1 may also play a role in the formation of the endothelium that gives rise to the blood brain barrier. EPAS1 is a potent activator of the Tie-2 tyrosine kinase expression. The activation seems to require recruitment of transcriptional coactivators such as CREBPB and probably EP300. Interaction of EPAS1 with redox regulatory protein APEX seems to activate CTAD.
