Web11 de abr. de 2024 · HIF-α family members are the key regulators of HIF activity and predominantly include HIF-1α and HIF-2α. HIF-α proteins are hydroxylated by PDH with O 2 as a substrate and subsequently degraded; therefore, the hydroxylation modification of HIF-α is inhibited, and HIF-α accumulates in the hypoxic microenvironment [ 5 ]. 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).
