Specificity

A BLAST analysis was used to suggest cross reactivity with Hif3a protein from mouse (100% homology) and rat (91% homology). Reactivity against human Hif3a is not expected as only 75% homology for the immunizing sequence is noted. No reactivity is expected against other forms of Hif proteins. Reactivity against homologues from other sources is not known.

HIF3 alpha also known as IPAS stands as a unique member of the hypoxia-inducible factor (HIF) family involved in oxygen regulation. HIF3 alpha is a transcription factor made of approximately 66 kDa protein mass which plays a role in controlling gene expression in response to low oxygen conditions. It gets expressed in various tissues including the brain lungs and kidneys. Unlike HIF1 alpha and HIF2 alpha HIF3 alpha can act as negative regulator of HIF-mediated gene activation by forming complexes with other HIFs impeding their transcriptional ability.
Biological function summary

HIF3 alpha engages in cellular response to hypoxic environments by binding to hypoxia-responsive elements in DNA. It forms heterodimers with ARNT an aryl hydrocarbon receptor nuclear translocator allowing interaction with DNA sequences needed for hypoxia response. HIF3 alpha differs by sometimes inhibiting rather than activating target genes providing a balance to the functions of other HIFs. It affects vascular development and energy metabolism performing roles outside traditional hypoxia response.

Pathways

HIF3 alpha integrates into key biological networks such as the HIF signaling pathway and oxygen homeostasis. Within these pathways it interacts with other HIF family members including HIF1 alpha and HIF2 alpha regulating downstream hypoxia-adaptive responses. This interaction allows a fine-tuned balance in the expression of genes linked to angiogenesis and erythropoiesis exemplifying its antagonistic function in comparison to other HIFs that usually activate these pathways.

HIF3 alpha assumes significant roles in the context of conditions like non-small cell lung carcinoma (NSCLC) and sleep apnea. Studies suggest alterations in HIF3 alpha expression contribute to tumor progression in NSCLC and the regulation of respiratory drive under low oxygen conditions in sleep apnea. Through these disease processes potential connections with proteins like VEGF (Vascular Endothelial Growth Factor) underline HIF3 alpha's modulatory impact in angiogenic activity and hypoxic responses affecting disease progression and outcomes.

Target data

Acts as a transcriptional regulator in adaptive response to low oxygen tension. Acts as a regulator of hypoxia-inducible gene expression (PubMed : 11734856, PubMed : 21546903, PubMed : 9840812). Plays a role in the development of the cardiorespiratory system (PubMed : 18070924).. Isoform 1. Acts as a positive regulator of hypoxia-inducible gene expression. Associates to core DNA sequence 5'-TACGTG-3' within the hypoxia response element (HRE) of target gene promoters in a ARNT-dependent manner, and hence also participates in the transcriptional activation of reporter genes driven by HRE (PubMed : 9840812).. Isoform 2. Attenuates the ability of transcription factor HIF1A, EPAS1 and the HIF1A-ARNT complex to bind to hypoxia-responsive elements (HRE) located within the enhancer/promoter of hypoxia-inducible target genes and hence inhibits HRE-driven transcriptional activation. Functions as an inhibitor of angiogenesis in hypoxic cells of the cornea. May act as a tumor suppressor (PubMed : 11734856). May also be involved in apoptosis (PubMed : 21546903).. Isoform 3. Attenuates the ability of transcription factor HIF1A, EPAS1 and the HIF1A-ARNT complex to bind to hypoxia-responsive elements (HRE) located within the enhancer/promoter of hypoxia-inducible target genes and hence inhibits HRE-driven transcriptional activation (PubMed : 18070924). Also plays a role in the development of the lung and heart during embryonic and neonatal stages (PubMed : 18070924).
