Hypoxia-inducible factor (HIF) is a sequence-specific DNA-binding protein that can promote or repress the transcription of a broad range of genes that are involved in maintaining biological homeostasis. HIF is mostly non-functional in oxygenated cells but becomes active under specific conditions, including lowoxygen (hypoxic) stress. HIF is a heterodimeric complex that is composed of an oxygen-...
