Euchromatinization
WebMeiotic inactivation of these chromosomes is therefore unlikely. In the oocytes of ZW females, meiotic pairing failure is avoided through euchromatinization of the W rather than heterochromatinization of the Z chromosome. Since both chromosomes are euchromatic, recombination should occur. WebApr 4, 2024 · These data suggest a model where the deacetylase activity of Sir2 prevents euchromatinization of the ribosomal DNA and silences naturally occurring intergenic transcription units. SIR2 affects DNA topology by increasing negative supercoiling. Recognition of the binding partners of Sir2 is a key function of non-conserved sequences.

WebSep 18, 2009 · Although nuclear compartmentalization, chromatin accessibility, and spatial sequestration of genes and their regulatory factors serve to modulate the output and functional status of genomes, the principles of the cellular organization of genomes and reorganization of nuclear architecture are still elusive (Misteli 2007 ). WebMay 25, 2024 · We demonstrated that the KDM4B-CCAR1-MED1 signaling axis induces changes in chromatin structure (euchromatinization) near the promoters of osteoclast-related genes through H3K9 demethylation, leading to NF-κB p65 recruitment via a direct interaction between KDM4B and p65.
