Hypoxia-inducible factor 1-alpha, also known as HIF-1-alpha, is a subunit of a heterodimeric transcription factor hypoxia-inducible factor 1 (HIF-1) that is encoded by the HIF1A gene. The Nobel Prize in Physiology or Medicine 2024 was awarded for the discovery of HIF. HIF1A is a basic helix-loop-helix … Ver mais HIF1 is a heterodimeric basic helix-loop-helix structure that is composed of HIF1A, the alpha subunit (this protein), and the aryl hydrocarbon receptor nuclear translocator (Arnt), the beta subunit. HIF1A contains a … Ver mais The transcription factor HIF-1 plays an important role in cellular response to systemic oxygen levels in mammals. HIF1A activity is … Ver mais HIF1A is overexpressed in many human cancers. HIF1A overexpression is heavily implicated in promoting tumor growth and metastasis through its role in initiating angiogenesis and … Ver mais • Hypoxia inducible factors Ver mais The human HIF1A gene encodes for the alpha subunit, HIF1A of the transcription factor hypoxia-inducible factor (HIF1). Its protein expression … Ver mais HIF1A abundance (and its subsequent activity) is regulated transcriptionally in an NF-κB-dependent manner. In addition, the coordinated activity of the prolyl hydroxylases (PHDs) maintain the appropriate balance of HIF1A protein in the post-translation … Ver mais HIF1A has been shown to interact with: • ARNTL, • ARNT, • CREBB, • EP300, Ver mais Webin expression of HIF1 target genes involved in tumour progression. Protein-protein interaction analysis demonstrated that RB exists in complex with ARNT and TRIP230. Moreover, this complex dissociated in the presence of an ARNT-interacting peptide. Lastly, the C-terminal region of the TRIP230 RB-interaction domain has been identified
