    Molecular features underlying differential SHP1/SHP2 binding of immune checkpoint receptors

    Xiaozheng Xu, Takeya Masubuchi ... Enfu Hui
    A molecular interpretation is provided for why some inhibitory immunoreceptors prefer to recruit SHP1 but others prefer SHP2.

    The mesoscale organization of syntaxin 1A and SNAP25 is determined by SNARE–SNARE interactions

    Jasmin Mertins, Jérôme Finke ... Thorsten Lang
    SNARE–SNARE interactions that have previously only been proposed to participate in membrane fusion on the nanoscale also serve to organize SNARE domains on the mesoscale.

    Sumoylation of the human histone H4 tail inhibits p300-mediated transcription by RNA polymerase II in cellular extracts

    Calvin Jon A Leonen, Miho Shimada ... Champak Chatterjee
    Chemically sumoylated histone H4 shows negative biochemical crosstalk with gene-activating histone acetylation and methylation marks, and directly inhibits RNA polymerase II-mediated gene transcription.

    The molecular appearance of native TRPM7 channel complexes identified by high-resolution proteomics

    Astrid Kollewe, Vladimir Chubanov ... Thomas Gudermann
    High-resolution proteomics in conjunction with biochemical and electrophysiological experiments revealed that the channel-kinase TRPM7 in rodent brain forms macromolecular complexes containing the metal transporters CNNM1-4 and a small G-protein ARL15.

    The hepatic AMPK-TET1-SIRT1 axis regulates glucose homeostasis

    Chunbo Zhang, Tianyu Zhong ... Jianing Zhong
    A series of experiments at the molecular level reveal the underlying mechanism of how a gene activates liver glucose production to regulate the blood glucose metabolism in mice.

    Dysfunctional TRPM8 signalling in the vascular response to environmental cold in ageing

    Dibesh Thapa, Joäo de Sousa Valente ... Susan D Brain
    Cold detecting thermoreceptor TRPM8's signalling is diminished with ageing which leads to an impaired response to cold observed in ageing.

    Immunomodulatory drug discovery from herbal medicines: Insights from organ-specific activity and xenobiotic defenses

    Jue Shi, Jui-Hsia Weng, Timothy J Mitchison
    Organ-selective drug action of traditional Chinese medicine that generates systemic immune mediators is proposed and reviewed as a novel mechanistic angle to develop new immunomodulatory drugs.

    Short-chain fatty acids activate acetyltransferase p300

    Sydney P Thomas, John M Denu
    At most physiological concentrations, the short-chain fatty acids propionate and butyrate affect histone acetylation by modifying and activating the acetyltransferase p300/CBP, rather than by inhibiting histone deacetylases.
