    Integrated analysis of H2A.Z isoforms function reveals a complex interplay in gene regulation

    Assala Lamaa, Jonathan Humbert ... Didier Trouche
    The two H2A.Z isoforms have specific interactors which mediate their differential effects on gene expression.

    Translational initiation in E. coli occurs at the correct sites genome-wide in the absence of mRNA-rRNA base-pairing

    Kazuki Saito, Rachel Green, Allen R Buskirk
    E. coli ribosomes incapable of base-pairing with the Shine-Dalgarno sequence are still selective for annotated start sites, indicating these sites are hard-wired for initiation by other mRNA features.

    Loss of Kat2a enhances transcriptional noise and depletes acute myeloid leukemia stem-like cells

    Ana Filipa Domingues, Rashmi Kulkarni ... Cristina Pina
    Histone acetyl-transferase Kat2a preserves leukemia stem cells through frequent transcriptional firing of metabolic and regulatory gene promoters and maintenance of a largely invariant self-renewal program.

    Structural basis for COMPASS recognition of an H2B-ubiquitinated nucleosome

    Evan J Worden, Xiangbin Zhang, Cynthia Wolberger
    The structure of the COMPASS methyltransferase bound to an H2B-ubiquitinated nucleosome provides insights into mechanisms of trans-histone cross-talk and the dynamic role of H2B ubiquitination in stimulating histone methylation.

    Histone Methylation: Navigating the structure of COMPASS

    Karolin Luger, Jonathan W Markert
    Cryo-electron microscopy reveals how ubiquitination promotes the methylation of histone H3 by the histone-modifying complex COMPASS.

    Cdc7 activates replication checkpoint by phosphorylating the Chk1-binding domain of Claspin in human cells

    Chi-Chun Yang, Hiroyuki Kato ... Hisao Masai
    Cdc7 and CK1g1 independently and additively phosphorylate the Chk1-binding domain of claspin to activate replication checkpoint with differential contribution of each kinase in different cell types.

    TRF1 averts chromatin remodelling, recombination and replication dependent-break induced replication at mouse telomeres

    Rosa Maria Porreca, Emilia Herrera-Moyano ... Jean-Baptiste Vannier
    TRF1 suppresses replication fork stalling, which triggers break induced replication at telomeres associated with DNA damage response, alteration in the telomere chromatin environment, and re-localisation of telomeres to PML bodies.

    Repressive H3K9me2 protects lifespan against the transgenerational burden of COMPASS activity in C. elegans

    Teresa Wei-sy Lee, Heidi Shira David ... David John Katz
    The transgenerational inheritance of lifespan is facilitated by the accumulation of repressive chromatin across generations.

    Epigenetics: A memory of longevity

    Felicity Emerson, Cheng-Lin Li, Siu Sylvia Lee
    Worms with increased levels of the epigenetic mark H3K9me2 have a longer lifespan that can be passed down to future generations.

    Two roles for the yeast transcription coactivator SAGA and a set of genes redundantly regulated by TFIID and SAGA

    Rafal Donczew, Linda Warfield ... Steven Hahn
    The transcription coactivators SAGA and TFIID have redundant function at a subset of yeast genes while SAGA also contributes to transcription of all genes through regulation of chromatin modifications.
