NCBI Description
regulates transcription in response to low oxygen; may play a role in vascular biology [RGD, Feb 2006]
Uniprot Description
HIF1A: a master transcriptional regulator of the adaptive response to hypoxia. Under hypoxic conditions, activates the transcription of over 40 genes, including erythropoietin, glucose transporters, glycolytic enzymes, vascular endothelial growth factor, HILPDA, and other genes whose protein products increase oxygen delivery or facilitate metabolic adaptation to hypoxia. Plays an essential role in embryonic vascularization, tumor angiogenesis and pathophysiology of ischemic disease. Binds to core DNA sequence 5'-[AG]CGTG-3' within the hypoxia response element (HRE) of target gene promoters. Activation requires recruitment of transcriptional coactivators such as CREBPB and EP300. Activity is enhanced by interaction with both, NCOA1 or NCOA2. Interaction with redox regulatory protein APEX seems to activate CTAD and potentiates activation by NCOA1 and CREBBP. Involved in the axonal distribution and transport of mitochondria in neurons during hypoxia. Interacts with the HIF1A beta/ARNT subunit; heterodimerization is required for DNA binding. Interacts with COPS5; the interaction increases the transcriptional activity of HIF1A through increased stability. Interacts with EP300 (via TAZ-type 1 domains); the interaction is stimulated in response to hypoxia and inhibited by CITED2. Interacts with CREBBP (via TAZ-type 1 domains). Interacts with NCOA1, NCOA2, APEX and HSP90. Interacts (hydroxylated within the ODD domain) with VHLL (via beta domain); the interaction, leads to polyubiquitination and subsequent HIF1A proteasomal degradation. During hypoxia, sumoylated HIF1A also binds VHL; the interaction promotes the ubiquitination of HIF1A. Interacts with SENP1; the interaction desumoylates HIF1A resulting in stabilization and activation of transcription. Interacts (Via the ODD domain) with ARD1A; the interaction appears not to acetylate HIF1A nor have any affect on protein stability, during hypoxia. Interacts with RWDD3; the interaction enhances HIF1A sumoylation. Interacts with TSGA10. Interacts with RORA (via the DNA binding domain); the interaction enhances HIF1A transcription under hypoxia through increasing protein stability. Interaction with PSMA7 inhibits the transactivation activity of HIF1A under both normoxic and hypoxia- mimicking conditions. Interacts with USP20. Interacts with RACK1; promotes HIF1A ubiquitination and proteasome- mediated degradation. Interacts (via N-terminus) with USP19. Under reduced oxygen tension. Induced also by various receptor-mediated factors such as growth factors, cytokines, and circulatory factors such as PDGF, EGF, FGF2, IGF2, TGFB1, HGF, TNF, IL1B, angiotensin-2 and thrombin. However, this induction is less intense than that stimulated by hypoxia. Repressed by HIPK2 and LIMD1. Expressed in most tissues with highest levels in kidney and heart. Overexpressed in the majority of common human cancers and their metastases, due to the presence of intratumoral hypoxia and as a result of mutations in genes encoding oncoproteins and tumor suppressors. 2 isoforms of the human protein are produced by alternative splicing.

Product Notes
The HIF1A hif1a (Catalog #AAA8226858) is a siRNA produced from Synthetic and is intended for research purposes only. The product is available for immediate purchase. The HIF1A siRNA (Rat) reacts with Rat and may cross-react with other species as described in the data sheet. AAA Biotech's HIF1A can be used in a range of immunoassay formats including, but not limited to, RNA Interference (RNAi). Researchers should empirically determine the suitability of the HIF1A hif1a for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "HIF1A, siRNA" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
