Auts2 | Autism susceptibility gene 2 protein homolog; Component of a Polycomb group (PcG) multiprotein PRC1-like complex, a complex class required to maintain the transcriptionally repressive state of many genes, including Hox genes, throughout development. PcG PRC1 complex acts via chromatin remodeling and modification of histones; it mediates monoubiquitination of histone H2A 'Lys-119', rendering chromatin heritably changed in its expressibility. The PRC1-like complex that contains PCGF5, RNF2, CSNK2B, RYBP and AUTS2 has decreased histone H2A ubiquitination activity, due to the phosphorylati [...] (1013 aa) | ||||
Hif3a | Hypoxia-inducible factor 3-alpha; Acts as a transcriptional regulator in adaptive response to low oxygen tension. Acts as a regulator of hypoxia-inducible gene expression. Plays a role in the development of the cardiorespiratory system. [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 ac [...] (664 aa) |
