[[https://www.uniprot.org/uniprot/EPAS1_HUMAN EPAS1_HUMAN]] Defects in EPAS1 are the cause of familial erythrocytosis type 4 (ECYT4) [MIM:[https://omim.org/entry/611783 611783]]. ECYT4 is an autosomal dominant disorder characterized by increased serum red blood cell mass, elevated hemoglobin concentration and hematocrit, and normal platelet and leukocyte counts.<ref>PMID:19208626</ref> <ref>PMID:18378852</ref> <ref>PMID:18184961</ref> <ref>PMID:22367913</ref>

[[https://www.uniprot.org/uniprot/EPAS1_HUMAN EPAS1_HUMAN]] Transcription factor involved in the induction of oxygen regulated genes. Binds to core DNA sequence 5'-[AG]CGTG-3' within the hypoxia response element (HRE) of target gene promoters. 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. May also play a role in the formation of the endothelium that gives rise to the blood brain barrier. Potent activator of the Tie-2 tyrosine kinase expression. Activation seems to require recruitment of transcriptional coactivators such as CREBPB and probably EP300. Interaction with redox regulatory protein APEX seems to activate CTAD. [[https://www.uniprot.org/uniprot/ARNT_HUMAN ARNT_HUMAN]] Required for activity of the Ah (dioxin) receptor. This protein is required for the ligand-binding subunit to translocate from the cytosol to the nucleus after ligand binding. The complex then initiates transcription of genes involved in the activation of PAH procarcinogens. The heterodimer with HIF1A or EPAS1/HIF2A functions as a transcriptional regulator of the adaptive response to hypoxia.
