The deposition of H3 lysine 27 tri-methylation … WebWe show that one role of H3K27me3 is to allow PcG complexes anchored at PREs to interact with surrounding chromatin. In contrast, the bulk of H2AK118ub is unrelated to PcG repression. These findings radically change our view of how PcG repression is targeted and suggest that PRC1 and PRC2 can communicate independently of histone modifications. WebMar 17, 2024 · This scheme introduces the existence of PRC2-independent PRC1 sub-complexes that bind the same genomic loci independently of H3K27me3 and play a major contribution to sustain H2Aubq levels; B) The "PRC1-dependent" model shows that PRC2 can be directly recruited to chromatin by variant PRC1 sub-complexes, potentially by … mcdonalds code of practice
