功能Involved in adaptive response to hypoxia. Suppresses hypoxia-inducible expression of HIF1A and EPAS1. Binds to core DNA sequence 5'-TACGTG-3' within the hypoxia response element (HRE) of target gene promoters. The complex HIF3A-ARNT activates the transcription of reporter genes driven by HRE. Isoform 4 has a dominant-negative function of inactivating HIF1A-mediated transcription. Isoform 4 attenuates the binding of HIF1A to hypoxia-responsive elements (HRE), thus inhibiting HRE-driven transcription. Hypoxia induces down-regulation of isoform 4, leading to activation of HIF1A in hypoxia. Conversely, upon restoring normoxia, the expression of isoform 4 increases and thereby secure an inhibition of HIF1A activity. Isoform 4 may be a negative regulator of hypoxia-inducible gene expression in the kidney and may be involved in renal tumorigenesis. Functions as an inhibitor of angiogenesis in the cornea.
组织特异性Expressed in kidney. Expressed abundantly in lung epithelial cells. Expression is regulated in an oxygen-dependent manner.
序列相似性Contains 1 basic helix-loop-helix (bHLH) domain.
Contains 2 PAS (PER-ARNT-SIM) domains.
翻译后修饰In normoxia, hydroxylated on Pro-492 in the oxygen-dependent degradation domain (ODD) by PHD. The hydroxylated proline promotes interaction with VHL, initiating rapid ubiquitination and subsequent proteasomal degradation.
细胞定位Nucleus. Cytoplasm. In the nuclei of all periportal and perivenous hepatocytes. In the distal perivenous zone, detected in the cytoplasm of the hepatocytes.

Anti-HIF3 alpha/IPAS antibody (ab2165) at 1/1600 dilution + 3T3 lysate treated with Cobalt (II) chloride at 10 µg/ml
Goat-anti-Rabbit at 1/10000 dilution
Predicted band size: 72 kDa
Observed band size: 72 kDa
Additional bands at: 24 kDa, 55 kDa. We are unsure as to the identity of these extra bands.
Exponentially growing 3T3 cells were treated with 130µM CoCl2 for 6 hours at 37°C to mimic hypoxia. A clear band at ~ 72kDa is detected in this lysate although some weaker background staining is also seen.
