Description

Mouse Monoclonal Antibody

This ESEE122 MAb reacts with hypoxia inducible factor-1 alpha. The hypoxia inducible factor (HIF-1) is a transcription factor composed of an inducible alpha form and the constitutively expressed beta form, also called the aryl hydrocarbon receptor nuclear translocator (ARNT). Both alpha and beta subunits of HIF-1 contain basic helix-loop-helix motifs and function to activate transcription of genes in response to reduced oxygen levels. Under normoxic conditions, HIF-1 alpha is rapidly degraded, while HIF-1 alpha expression is induced and degradation inhibited under hypoxic conditions. HIF-1 alpha can be found in the cytoplasm and/or in the nucleus under normoxic conditions, but translocates to the nucleus under hypoxic conditions. HIF-1 is upregulated in several cancer types and functions to control genes involved in angiogenesis, cell survival and T cell development. Recent studies have shown the importance of HIF-1 alpha in balancing Th17 and Treg development. This ESEE122 antibody has also been reported to cross-react with bovine, rat, and mouse hypoxia inducible factor-1 alpha.

HIF1-alpha (HIF1A) is a subunit of HIF1, which is a transcription factor found in mammalian cells cultured under reduced oxygen tension. HIF-1 is a heterodimer consisting of an alpha and beta subunit, both belonging to the basic-helix-loop-helix Per-aryl hydrocarbon receptor nuclear translocator-Sim (PAS) family of transcription factors. HIF1 functions as a transcriptional regulator of the adaptive response to hypoxia. Under hypoxic conditions, HIF-1 activates the transcription of over 40 genes, including erythropoietin, glucose transporters, glycolytic enzymes, vascular endothelial growth factor, HILPDA, and other genes whose protein products increase oxygen delivery or facilitate metabolic adaptation to hypoxia. HIF1-alpha regulates hypoxia-mediated apoptosis, cell proliferation and tumor angiogenesis. Hypoxia which induces p53 protein accumulation, directly interacts with HIF1-alpha and reduces hypoxia-induced expression of HIF1-alpha by promoting MDM2-mediated ubiquitination and proteasomal degradation under hypoxic conditions. Recent studies suggest that induction of NOX4 by HIF1-alpha contributes to maintain ROS levels after hypoxia and hypoxia-induced proliferation. In humans, it is located on the q arm of chromosome 14. The C-terminal of HIF1A binds to p300. p300/CBP-HIF complexes participate in the induction of hypoxia-responsive genes, including VEGF. Hypoxia contributes significantly to the pathophysiology of major categories of human disease, including myocardial and cerebral ischemia, cancer, pulmonary hypertension, congenital heart disease and chronic obstructive pulmonary disease.
