Cbx2 phase separation
WebJun 6, 2024 · Point mutations in an internal domain of Cbx2 eliminate phase separation. These same point mutations eliminate the formation of puncta in cells and have been shown previously to eliminate nucleosome compaction in vitro and generate axial patterning defects in mice. Thus, the domain of CBX2 that is important for phase separation is the same ...

WebCbx2 undergoes phase separation to form condensates. Cbx2 condensates exhibit liquid-like properties and can concentrate DNA and nucleosomes. We demonstrate that the conserved residues within the IDR promote the condensate formation in vitro and in vivo. We further indicate that H3K27me3 has minimal effects on the Cbx2 condensate … WebApr 1, 2024 · As mentioned in the previous section, CBX2 drives the formation of CBX2–PRC1 protein condensates, which in turn compact and organize chromatin regions decorated with H3K27me3 [ 23 • ]. In Arabidopsis, H3K27me3-marked chromatin is enriched for long-range promoter-promoter interactions [ 36 ].
WebDec 27, 2024 · Here, by using biochemical reconstitution, cellular imaging, and multiscale molecular simulations, we show that PRC1 condensates are assembled via a scaffold-client liquid-liquid phase...
