Web1 de nov. de 2006 · The primary factor mediating this response is the hypoxia-inducible factor-1 (HIF-1), an oxygen-sensitive transcriptional activator. HIF-1 consists of a constitutively expressed subunit HIF-1β and an oxygen-regulated subunit HIF-1α (or its paralogs HIF-2α and HIF-3α). The stability and activity of the α subunit of HIF are … 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 basic helix-loop-helix domain near the C-terminal, followed by two distinct PAS … Ver mais 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 … Ver mais The transcription factor HIF-1 plays an important role in cellular response to systemic oxygen levels in mammals. HIF1A activity is regulated by a host of post-translational modifications: hydroxylation, acetylation, and phosphorylation. … Ver mais HIF1A is overexpressed in many human cancers. HIF1A overexpression is heavily implicated in promoting tumor growth and metastasis through … 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 level can be measured by antibodies … 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, • HIF1AN, Ver mais
