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.
Upon genotoxic stress, the FBXL10-RNF68-RNF2 ubiquitin ligase complex mono-ubiquitylates histone H2A and mediates H2A/H2A.Z exchange to repress transcription and ensures proper high fidelity homologous recombination repair.
Calcium-calcineurin signaling cascade drives the acquisition of both the phenotype of the most self-reactive naive CD4 T cells and their enhanced cell-intrinsic ability to commit into induced regulatory T cells upon activation.
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.
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.
