Chromatin & Epigenetics
Structural basis of nucleosomal histone H4 lysine 20 methylation by SET8 methyltransferaseCryo-EM structures of the human SET8–nucleosome complexes reveal the mechanism by which the SET8 methyltransferase binds the nucleosome and specifically recognizes the histone H4 lysine-20 residue.
Different mutant RUNX1 oncoproteins program alternate haematopoietic differentiation trajectoriesUsing integrated genome-wide and phenotypic methods this study investigates four different mutant RUNX1 oncoproteins and reveals how they differentially contribute to aberrant haematopoiesis.
The uncharacterized protein FAM47E interacts with PRMT5 and regulates its functionsThe uncharacterized protein FAM47E interacts with and stabilizes the protein arginine methyltransferase PRMT5, regulating its epigenetic functions thereby modulating target gene expression.
The chromatin landscape of primary synovial sarcoma organoids is linked to specific epigenetic mechanisms and dependenciesWe have addressed the mechanisms by which the fusion protein SS18-SSX modifies the epigenome toward the development of synovial sarcoma and the establishment of its potentially targetable vulnerabilities.
Polycomb mutant partially suppresses DNA hypomethylation–associated phenotypes in ArabidopsisA mutation in Arabidopsis polycomb repressive complex 2 partially suppresses the transposon activity observed in a DNA methylation mutant, challenging expectations.
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.
