HIF-1 alpha is a key protein that responds to low oxygen levels. HIF-1 alpha Protein, Human (His) is the recombinant human-derived HIF-1 alpha protein, expressed by E. coli , with N-His labeled tag.

Human

HIF-1 alpha functions as a master transcriptional regulator orchestrating the adaptive response to hypoxia, activating the transcription of over 40 genes critical for oxygen delivery, metabolic adaptation, and cellular response to low oxygen levels. Its target genes include erythropoietin, glucose transporters, glycolytic enzymes, vascular endothelial growth factor, and HILPDA. This protein plays essential roles in embryonic vascularization, tumor angiogenesis, and the pathophysiology of ischemic diseases. HIF-1 alpha forms a heterodimer with ARNT, binding to the hypoxia response element (HRE) in target gene promoters. Its activation requires coactivators such as CREBBP and EP300, and its activity is enhanced by interaction with NCOA1, NCOA2, and APEX1. Furthermore, HIF-1 alpha is involved in axonal distribution and mitochondrial transport in neurons during hypoxia and, upon infection by SARS-CoV-2, contributes to the induction of glycolysis and a pro-inflammatory state in monocytes. It induces the expression of ACE2 and cytokines, promoting SARS-CoV-2 replication and monocyte inflammatory response.
