    PCGF6-PRC1 suppresses premature differentiation of mouse embryonic stem cells by regulating germ cell-related genes

    Mitsuhiro Endoh, Takaho A Endo ... Haruhiko Koseki
    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.

    PRC1 sustains the integrity of neural fate in the absence of PRC2 function

    Ayana Sawai, Sarah Pfennig ... Jeremy S Dasen
    Regulation of neuronal diversity and fate through protein complexes involved in gene repression and chromatin condensation.

    RYBP stimulates PRC1 to shape chromatin-based communication between Polycomb repressive complexes

    Nathan R Rose, Hamish W King ... Robert J Klose
    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 control of PRC1 reveals its role in chromosome alignment on the spindle by overlap length-dependent forces

    Mihaela Jagrić, Patrik Risteski ... Iva M Tolić
    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.

    KDM2B links the Polycomb Repressive Complex 1 (PRC1) to recognition of CpG islands

    Anca M Farcas, Neil P Blackledge ... Robert J Klose
    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.

    Interactions with RNA direct the Polycomb group protein SCML2 to chromatin where it represses target genes

    Roberto Bonasio, Emilio Lecona ... Danny Reinberg
    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.

    Geometry of antiparallel microtubule bundles regulates relative sliding and stalling by PRC1 and Kif4A

    Sithara Wijeratne, Radhika Subramanian
    Geometrical features of microtubule arrays regulate the collective activity of motor and non-motor proteins.

    Live-cell single-molecule tracking reveals co-recognition of H3K27me3 and DNA targets polycomb Cbx7-PRC1 to chromatin

    Chao Yu Zhen, Roubina Tatavosian ... Xiaojun Ren
    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.

    Human DCP1 is crucial for mRNA decapping and possesses paralog-specific gene regulating functions

    Ting-Wen Chen, Hsiao-Wei Liao ... Chung-Te Chang
    For mRNA decapping by enhancing DCP2's mRNA-binding affinity and regulating distinct biological processes through DCP1a and DCP1b, human DCP1 is essential.

    YAP/TAZ enhances P-body formation to promote tumorigenesis

    Xia Shen, Xiang Peng ... Chen-Ying Liu
    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.
