The antiviral and genomic DNA deaminase APOBEC3B is repressed in normal cells by PRC1.6/E2F6 and DREAM/E2F4 complexes and deregulation of this axis provides a unifying mechanism for overexpression in cancer.
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.
Heat shock induces relocalization of epigenetic modifiers to the nucleolus, which acts as a dedicated protein quality control center that is indispensable for recovery of epigenetic regulators and epigenetic modifications.
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.
The ZF-CxxC protein FBXL19 recruits kinase-associated Mediator to CpG islands of silent developmental genes in embryonic stem cells, which primes these genes for activation during differentiation and is required for embryonic development.
Directly exerting force on the mammalian spindle reveals local and short-lived reinforcement in the spindle center, well-suited to preserve connections to chromosomes over seconds and yet allow remodeling over minutes.
