    SUV39 SET domains mediate crosstalk of heterochromatic histone marks

    Alessandro Stirpe, Nora Guidotti ... Thomas Schalch
    Clr4, a highly conserved SUV39 histone methyltransferase, requires its SET domain to sense histone H3K14 ubiquitination in order to maintain heterochromatin and H3K9 methylation.

    Inhibition of DNMT1 methyltransferase activity via glucose-regulated O-GlcNAcylation alters the epigenome

    Heon Shin, Amy Leung ... Dustin E Schones
    Extracellular glucose promotes O-GlcNAcylation of DNMT1 and inhibition of DNMT1 function in the maintenance of genomic methylation.

    Multisite dependency of an E3 ligase controls monoubiquitylation-dependent cell fate decisions

    Achim Werner, Regina Baur ... Michael Rape
    Simultaneous phosphorylation of multiple substrate motifs drives switch-like target recognition and monoubiquitylation by an E3 ligase during metazoan development.

    Rapid translocation of NGR proteins driving polarization of PIN-activating D6 protein kinase during root gravitropism

    Ivan Kulich, Julia Schmid ... Jiří Friml
    Negative Gravitropic Response of roots (NGRs), pivotal for root gravitropic bending, are indispensable for the gravity-induced translocation of D6 protein kinase, a key regulator of PIN3 auxin efflux carrier activity.

    Explicit ion modeling predicts physicochemical interactions for chromatin organization

    Xingcheng Lin, Bin Zhang
    The physicochemical interactions among wild-type nucleosomes hold substantial significance and play a role in chromatin folding under physiological salt concentrations.

    Interplay between acetylation and ubiquitination of imitation switch chromatin remodeler Isw1 confers multidrug resistance in Cryptococcus neoformans

    Yang Meng, Yue Ni ... Chen Ding
    Isw1 acts as a master regulator in modulating the expression of drug-resistance genes, and this regulatory mechanism is dependent on the interaction of Isw1 acetylation and ubiquitination.

    Vitamin D induces SIRT1 activation through K610 deacetylation in colon cancer

    José Manuel García-Martínez, Ana Chocarro-Calvo ... Custodia García-Jiménez
    Vitamin D bound to its receptor interacts with SIRT1 to induce its auto deacetylation and catalytic activity, which drives anti-proliferative effects in colorrectal cancer and this may lead to new therapeutic approaches for colorrectal and perhaps other cancers.

    A druggable secretory protein maturase of Toxoplasma essential for invasion and egress

    Sunil Kumar Dogga, Budhaditya Mukherjee ... Dominique Soldati-Favre
    An aspartyl protease is essential for the lytic cycle of Toxoplasma gondii and is involved in the maturation of proteins critical for invasion and egress, and it can be targeted selectively with an ethylamine scaffold based peptidomimetic inhibitor.

    Noncanonical usage of stop codons in ciliates expands proteins with structurally flexible Q-rich motifs

    Chi-Ning Chuang, Hou-Cheng Liu ... Ting-Fang Wang
    Noncanonical usage of stop codons in ciliates expands structurally flexible Q-rich domains and coevolves with codon usage biases to avoid triplet repeat disorders mediated by CAG/GTC replication slippage.

    The glucuronyltransferase B4GAT1 is required for initiation of LARGE-mediated α-dystroglycan functional glycosylation

    Tobias Willer, Kei-ichiro Inamori ... Kevin P Campbell
    Post-phosphoryl modification of α-dystroglycan requires the glucuronyltransferase B4GAT1; this enzyme synthesizes the acceptor glycan that serves as a primer for the glycosyltransferase LARGE to synthesize the laminin-binding glycan.
