The genomes of higher eukaryotes contain hundreds of genes that are regulated by Polycomb mechanisms. Once repressed by Polycomb complexes, they tend to stay repressed; but, when activated, they bind Trithorax protein …
Human Trithorax Protein hASH2 Functions as an Oncoprotein
WebNov 21, 2024 · Ash1 is an H3K36 methyltransferase, Trithorax group protein and is critical in antagonizing Polycomb silencing. Here, the authors purify the Drosophila Ash1 complex and identify Mrg15 and Nurf55 ... Trithorax-group proteins typically function in large complexes formed with other proteins. The complexes formed by TrxG proteins are divided into two groups: histone-modifying complexes and ATP-dependent chromatin-remodeling complexes. The main function of TrxG proteins, along with polycomb group (PcG) proteins, is regulating gene expression. Whereas PcG proteins are typically associated with gene silencing, TrxG proteins are most commonly linked to gene activati… fabickcat.com/online-tools
Polycomb group and trithorax group proteins in Arabidopsis
WebPolycomb group (PcG) proteins and trithorax group (TrxG) proteins are two classes of chromatin-modifying proteins that epigenetically regulate Hox gene expression. Both groups form multiprotein chromatin remodeling complexes that either repress (PcG) or activate transcription (TrxG).
