Mps2 links Csm4 and Mps3 to form a telomere-associated LINC complex in budding yeastThe canonical LINC complex is composed of two different transmembrane proteins; this work reveals the heterotrimeric composition of the telomere-associated LINC complex in budding yeast.
Stoichiometry of Rtt109 complexes with Vps75 and histones H3-H4The work determines the relative and absolute stoichiometry of a 5-chain protein complex involved in histone chaperoning and acetylation. Using sedimentation velocity and light scattering, it uncovers a dynamic equilibrium of complex self-association.
Biochemical and functional characterization of a meiosis-specific Pch2/ORC AAA+ assemblyThe AAA+ protein Pch2 forms a biochemical complex with Orc1/ORC to suppress DNA break formation in the meiotic G2/prophase.
CSDE1 controls gene expression through the miRNA-mediated decay machineryCSDE1 is a new component of miRNA-induced silencing complex and interacts with DCP1–DCP2 decapping machinery with potential roles in miRNA-mediated target degradation.
Splicing of enhancer-associated lincRNAs contributes to enhancer activityAnalysis of enhancer-associated lincRNA transcripts shows their efficient and conserved splicing contributes to cognate enhancer activity and cis-regulation of target gene expression.
Meiotic sex chromosome cohesion and autosomal synapsis are supported by Esco2This study reveals a role for the cohesin modifier ESCO2 for maintenance of sister chromatid cohesion in mammalian meiosis and a specific weakness of cohesion within male sex chromosome chromatin
Nup93 regulates breast tumor growth by modulating cell proliferation and actin cytoskeleton remodelingThis study highlights the role of Nup93-chromatin interactions in driving triple-negative breast cancer propagation through modulation of the actin cytoskeleton, cell migration and proliferation.
Oscillatory cAMP signaling rapidly alters H3K4 methylationThis work explores how GPCR-cAMP signaling dynamically influences histone methylation by altering intracellular labile Fe(II) levels and subsequently modulating histone demethylase activity.
Drug-induced chromatin accessibility changes associate with sensitivity to liver tumor promotionThis work explores quantitative chromatin accessibility, transcriptional and cis-acting gene regulatory variations underlying mouse strain–specific differences in drug-induced liver tumor promotion sensitivity.
Endogenous epitope-tagging of Tet1, Tet2 and Tet3 identifies TET2 as a naïve pluripotency markerExpression of TET proteins in pluripotent cell types is visualised by epitope tagging of endogenous alleles.
