CC -!- FUNCTION: Transcription factor involved in the induction of oxygen
CC regulated genes. Heterodimerizes with ARNT; heterodimer binds to core
CC DNA sequence 5'-TACGTG-3' within the hypoxia response element (HRE) of
CC target gene promoters (By similarity). Regulates the vascular
CC endothelial growth factor (VEGF) expression and seems to be implicated
CC in the development of blood vessels and the tubular system of lung. May
CC also play a role in the formation of the endothelium that gives rise to
CC the blood brain barrier. Potent activator of the Tie-2 tyrosine kinase
CC expression. Activation requires recruitment of transcriptional
CC coactivators such as CREBBP and probably EP300. Interaction with redox
CC regulatory protein APEX seems to activate CTAD (By similarity).
CC {ECO:0000250, ECO:0000250|UniProtKB:P97481}.
CC -!- SUBUNIT: Interacts with HIF3A2. Efficient DNA binding requires
CC dimerization with another bHLH protein. Heterodimerizes with ARNT;
CC heterodimer binds to core DNA sequence 5'-TACGTG-3' within the hypoxia
CC response element (HRE) of target gene promoters. Interacts with CREBBP
CC (By similarity). Interacts with EGLN1. Interacts with VHL (By
CC similarity). {ECO:0000250|UniProtKB:P97481,
CC ECO:0000250|UniProtKB:Q99814}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:P97481,
CC ECO:0000255|PROSITE-ProRule:PRU00981}. Nucleus speckle
CC {ECO:0000250|UniProtKB:P97481}. Note=Colocalizes with HIF3A in the
CC nucleus and speckles. {ECO:0000250|UniProtKB:P97481}.
CC -!- PTM: In normoxia, is probably hydroxylated on Pro-405 and Pro-530 by
CC EGLN1/PHD1, EGLN2/PHD2 and/or EGLN3/PHD3. The hydroxylated prolines
CC promote interaction with VHL, initiating rapid ubiquitination and
CC subsequent proteasomal degradation. Under hypoxia, proline
CC hydroxylation is impaired and ubiquitination is attenuated, resulting
CC in stabilization (By similarity). {ECO:0000250}.
CC -!- PTM: In normoxia, is hydroxylated on Asn-851 by HIF1AN thus probably
CC abrogating interaction with CREBBP and EP300 and preventing
CC transcriptional activation. {ECO:0000250}.
CC -!- PTM: Phosphorylated on multiple sites in the CTAD. {ECO:0000250}.
CC -!- PTM: The iron and 2-oxoglutarate dependent 3-hydroxylation of
CC asparagine is (S) stereospecific within HIF CTAD domains.
CC {ECO:0000250}.
