== Function ==
[https://www.uniprot.org/uniprot/HIF3A_HUMAN HIF3A_HUMAN] Acts as a transcriptional regulator in adaptive response to low oxygen tension. Acts as a regulator of hypoxia-inducible gene expression (PubMed:11573933, PubMed:16126907, PubMed:19694616, PubMed:20416395, PubMed:21069422). Functions as an inhibitor of angiogenesis in hypoxic cells of the cornea. Plays a role in the development of the cardiorespiratory system. May also be involved in apoptosis (By similarity).[UniProtKB:Q0VBL6]<ref>PMID:11573933</ref> <ref>PMID:16126907</ref> <ref>PMID:19694616</ref> <ref>PMID:20416395</ref> <ref>PMID:21069422</ref>  Isoform 2: Attenuates the ability of transcription factor HIF1A to bind to hypoxia-responsive elements (HRE) located within the enhancer/promoter of hypoxia-inducible target genes and hence inhibits HRE-driven transcriptional activation. Also inhibits hypoxia-inducible ARNT-mediated gene expression.<ref>PMID:11573933</ref>  Isoform 3: Attenuates the ability of transcription factor HIF1A to bind to hypoxia-responsive elements (HRE) located within the enhancer/promoter of hypoxia-inducible target genes and hence inhibits HRE-driven transcriptional activation.<ref>PMID:19694616</ref> <ref>PMID:20416395</ref> <ref>PMID:21069422</ref>  isoform 4: Attenuates the ability of transcription factor HIF1A and EPAS1/HIF2A 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:16126907, PubMed:17998805, PubMed:19694616, PubMed:20416395). May act as a tumor suppressor and inhibits malignant cell transformation (PubMed:17998805).<ref>PMID:16126907</ref> <ref>PMID:17998805</ref> <ref>PMID:19694616</ref> <ref>PMID:20416395</ref>  Isoform 5: Attenuates the ability of transcription factor HIF1A to bind to hypoxia-responsive elements (HRE) located within the enhancer/promoter of hypoxia-inducible target genes and hence inhibits HRE-driven transcriptional activation.<ref>PMID:21069422</ref>

== Publication Abstract from PubMed ==
Hypoxia-inducible transcription factors (HIF) form heterodimeric complexes that mediate cell responses to hypoxia. The oxygen-dependent stability and activity of the HIF-alpha subunits is traditionally associated to post-translational modifications such as hydroxylation, acetylation, ubiquitination, and phosphorylation. Here we report novel evidence showing that unsaturated fatty acids are naturally occurring, non-covalent structural ligands of HIF-3alpha, thus providing the initial framework for exploring its exceptional role as a lipid sensor under hypoxia.
