Description: Molecular oxygen (O2) is essential for mammalian metabolic processes such as oxidative phosphorylation. Thus, survival depends upon instantaneous transcriptional modulation of genes that maintain O2 homeostasis. Transcriptional control of several of these genes is mediated by hypoxia-inducible factor 1 (HIF-1). HIF-1 is a heterodimer whose alpha and beta subunits are members of the PAS family of basic helix-loop-helix (bHLH) transcription factors. Common structural features of these proteins are an N-terminal bHLH DNA-binding domain and multiple PAS domains that confer dimerization ability and target gene specificity. Members diverge in their C-terminal regions. HIF-1beta is also known as the arylhydrocarbon nuclear translocator which is part of the functional dioxin receptor. However, HIF-1alpha functions exclusively to mediate responses to O2 deprivation. It contains C-terminal and internal transactivation domains. Although HIF-1 aproteinlevels increase during hypoxia, it is unstable in the presence of O2 due to an oxygen-dependent degradation domain (ODD) that targets it for ubiquitination. Thus, HIF-1alpha is essential for functional HIF-1 to mediate gene transcription in response to hypoxia. This antibody is routinely tested by western blot analysis.

Characteristics: 1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Please refer to us for technical protocols.
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
