Summary
HIF1 alpha antibody recognizes HIF1 alpha (HIF1a) protein, which is a subunit of the heterodimeric transcription factor hypoxia-inducible factor-1 (HIF-1). HIF-1 is a master regulator of homeostatic adaption to hypoxia (low oxygen supply) in various physiological and pathological conditions including normal development and cancer.

Background
Hypoxia-inducible factor-1 (HIF1) is a transcription factor found in mammalian cells cultured under reduced oxygen tension that plays an essential role in cellular and systemic homeostatic responses to hypoxia. HIF1 is a heterodimer composed of an alpha subunit and a beta subunit. The beta subunit has been identified as the aryl hydrocarbon receptor nuclear translocator (ARNT). This gene encodes the alpha subunit of HIF-1. Overexpression of a natural antisense transcript (aHIF) of this gene has been shown to be associated with nonpapillary renal carcinomas. Two alternative transcripts encoding different isoforms have been identified. [provided by RefSeq]
