Rabbit polyclonal antibody to HIF1 beta / ARNTHypoxia 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. HIF1 is a nuclear protein involved in mammalian oxygen homeostasis. This occurs as a posttranslational modification by prolyl hydroxylation. HIF1 is a heterodimer composed of HIF1 alpha and HIF1 beta subunits. Both subunits are constantly translated. However, under normoxic conditions, human HIF1 alpha is hydroxylated at Pro402 or Pro564 by a set of HIF prolyl hydroxylases, is polyubiquinated, and eventually degraded in proteosomes. Under hypoxic conditions, the lack of hydroxylation prevents HIF degradation and increases transcriptional activity. Therefore, the concentration of HIF1 alpha increases in the cell. In contrast, HIF1 beta remains stable under either condition. HIF1 beta is a series of aryl hydrocarbon receptor nuclear translocator (ARNT) gene products.
