PCGF6 links sequence specific target recognition by the MAX/MGA transcription factor complex to PRC1 (polycomb repressive complex 1) -dependent transcriptional silencing of germ cell-specific genes in mouse pluripotent stem cells.
The E3 ubiquitin ligase activity of polycomb repressive complex 1 is stimulated by RYBP to support a histone modification-dependent communication between polycomb repressive complexes in mice.
Optogenetic experiments show that bridging microtubules buffer chromosome movements and promote their alignment through forces transferred to the associated kinetochore fibers, which rely on precise regulation of the overlap region.

A protein that can recognize regions of DNA with a high proportion of unmethylated CpG dinucleotides, and then recruit polycomb group proteins to these CpG islands, has been identified.
The Polycomb group protein SCML2 contributes to the assembly and gene silencing function of Polycomb Repressive Complex 1 (PRC1) and requires an RNA-binding region to reach chromatin targets.
Live-cell single-molecule tracking reveals that hierarchical cooperation within the Polycomb Cbx7 protein between the low-affinity H3K27me3-binding module and the high-affinity DNA-binding cassette targets Polycomb repressive complex 1 to chromatin.
For mRNA decapping by enhancing DCP2's mRNA-binding affinity and regulating distinct biological processes through DCP1a and DCP1b, human DCP1 is essential.
P-body is a new downstream effector of YAP/TAZ for tumorigenesis and tumor progression, suggesting disruption of P-bodies as a potential therapeutic strategy for tumors with active YAP.
