Hypoxia-inducible factor 3-alpha

Gene

Hif3a

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Acts as a transcriptional regulator in adaptive response to low oxygen tension. Acts as a regulator of hypoxia-inducible gene expression (PubMed:9840812, PubMed:11734856, PubMed:21546903). Plays a role in the development of the cardiorespiratory system (PubMed:18070924).4 Publications
Isoform 1: Acts as 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).1 Publication
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).2 Publications
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). Plays also a role in the development of the lung and heart during embryonic and neonatal stages (PubMed:18070924).1 Publication

Expressioni

Tissue specificityi

Isoform 3 is expressed in endothelial cells of vessels and capillaries in alveoli of the neonatal lung (at protein level) (PubMed:18070924). Expressed in lung, brain, heart and kidney (PubMed:9840812). Isoform 2 is expressed in heart and lung (PubMed:12119283). Isoform 2 is highly expressed in the epithelial cell layer of the cornea with lower expression in the layers of ganglion cells, inner nuclear cells, and rods and cones of the retina (PubMed:11734856). Isoform 2 is expressed in the cerebellum only in the Purkinje cell layer (PubMed:11734856).4 Publications

Developmental stagei

Isoform 3 is expressed in brain, heart, lung, liver and kidney at 15.5 dpc. Isoform 3 is expressed in heart, lung, liver and kidney at 18.5 dpc.1 Publication

Inductioni

Isoform 2 is up-regulated in corneal epithelium cells under hypoxia (at protein level) (PubMed:11734856). Isoform 2 is up-regulated by hypoxia in a HIF1A-dependent manner (PubMed:12119283, PubMed:17355974). Isoform 3 is up-regulated by hypoxia (PubMed:18070924).4 Publications
