    basic FUNCTION
  • involved in the induction of oxygen regulated genes and may be implicated in the development of blood vessels and the tubular system of lung
  • playing a role in the adaptation of the cardiac myocytes during heart failure as well as in the regulation of gene expression by hypoxia
  • involved in complex oxygen sensing, and influencing the relative contribution of aerobic and anaerobic metabolism and hence the maximum sustainable metabolic power for a given event duration
  • differentially binds and regulates transcription under hypoxia
  • EPAS1 acts downstream of PPARGC1A as a key regulator of a muscle fiber-type program and the adaptive response to exercise
  • regulated CD82 gene expression by binding to its HRE consensus sequence located within its first intron
  • is required to induce CD82 expression under hypoxia
  • HIF1A and EPAS1 play a critical role in cellular response to hypoxia
  • important role in the regulation of tumor progression under chronic hypoxia
  • opposite roles of HIF1A and EPAS1 in the regulation of IL8 expression in endothelial cells
  • key regulator in alveolar maturation and the production of phospholipids by Type II cells
  • CELLULAR PROCESS cell organization/biogenesis

    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • interacting with SOX9 (hypoxia, and more specifically EPAS1, promotes both SOX9-dependent and -independent factors important for cartilage homeostasis)
  • interacting with RICTOR (dependent only on the CRTC2 constituent Rictor)
  • regulating intronic hypoxia response elements of TWIST1
  • VHL appears to specifically repress EPAS1 in renal epithelia
  • EPAS1, but not HIF1A, interacted with KLHL20
  • KLHL20 as a EPAS1-interacting protein that increases the expression level of EPAS1 protein
  • potent and functional inducer of CEBPB expression in chondrocytes by the CEBPB promoter assay
  • cell & other
    REGULATION
    activated by hypoxia
    KLHL20, that increases EPAS1 activity through a VHL-independent pathway
    induced by IL-1beta at the transcriptional level
    Other regulated via SUMOylation, reducing its transcriptional activity
    regulated by VHL (regulate HIF-alpha proteolysis by acting as the recognition component of a ubiquitin ligase complex)
    VHL and RNF4 control the levels of sumoylated EPAS1
