Description: This ESEE122 monoclonal antibody 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.
