Web11 de abr. de 2024 · Hypoxia-inducible factor 1 (HIF-1) is a dimeric transcription factor composed of a β subunit and an α subunit that is inhibited by HIF prolyl hydroxylases (PHD) in normoxia. Hypoxia causes the destabilization of HIF-1α inhibitors and HIF-1 activation to elicit changes in gene expression. Web9 de out. de 2007 · FIH-1 (factor inhibiting HIF-1) is another α-ketoglutarate-dependent dioxygenase that hydroxylates Asn 803 and thereby blocks the interaction of HIF-1α with the coactivators p300 and CBP . A subset of genes regulated by HIF-1 genes appears to be particularly sensitive to O 2-dependent regulation by FIH-1 .

Web因为依赖氧气，所以氧气不足——氧气浓度不断降低的时候，HIF-1α的泛素化就会减少，于是HIF-1α的分解就会减少，而合成速率不变或者通过某些继发的转录或者翻译调节途径而增加，因此HIF-1α的浓度迅速增加，从而到细胞核里去促进转录等等。. 研究发现HIF-1α ... WebStructure of hypoxia inducible factor 1-α (HIF-1α). The NH2-terminal of HIF-1α and HIF-1β consists of bHLH (basic helix–loop–helix) and PAS (Per-ARNT-Sim homology) domains that are required for heterodimerization and DNA binding. The COOH-terminal of HIF-1α (residues 531–826) contains two transactivation domains (TADs).
