    Ca2+ signaling driving pacemaker activity in submucosal interstitial cells of Cajal in the murine colon

    Salah A Baker, Wesley A Leigh ... Kenton M Sanders
    An optogenetic dual-color Ca2+-imaging approach shows how submucosal pacemaker-cells, interstitial cells of Cajal, modulate smooth-muscle responses and drive colonic motility via complex Ca2+ signaling.

    Structural and mechanistic basis of the EMC-dependent biogenesis of distinct transmembrane clients

    Lakshmi E Miller-Vedam, Bastian Bräuning ... Jonathan S Weissman
    Structure-function characterization of the EMC's cytoplasmic, transmembrane, and lumenal domains reveal features critical for terminal helix insertion and a specialized role for the lumenal domain in polytopic membrane protein biogenesis.

    Manipulation of the human tRNA pool reveals distinct tRNA sets that act in cellular proliferation or cell cycle arrest

    Noa Aharon-Hefetz, Idan Frumkin ... Roni Rak
    Systematic CRISPR-based editing of tRNA genes revealed that different human cells that span a range of growth rates and different modes of proliferation states require diverse tRNA sets.

    Graded titin cleavage progressively reduces tension and uncovers the source of A-band stability in contracting muscle

    Yong Li, Anthony L Hessel ... Wolfgang A Linke
    Elastic forces generated by the giant protein titin define both passive and active tension of skeletal muscle fibers and protect the sarcomeric myosin filaments from severe disruption during contraction.

    Defining human mesenchymal and epithelial heterogeneity in response to oral inflammatory disease

    Ana J Caetano, Val Yianni ... Paul Sharpe
    Single cell transcriptomic analysis provides a reference map for human oral muscosa in health and disease and a framework for the development of new therapeutic strategies.

    Torsin ATPases influence chromatin interaction of the Torsin regulator LAP1

    Naemi Luithle, Jelmi uit de Bos ... Ulrike Kutay
    The INM protein LAP1B, an activator of Torsin ATPases, is a chromatin-binding factor that erroneously persists on mitotic chromatin if Torsin functionality is compromised, inducing chromosome segregation defects and binucleation.

    chTOG is a conserved mitotic error correction factor

    Jacob A Herman, Matthew P Miller, Sue Biggins
    The conserved chTOG protein is required to destabilize incorrect kinetochore-microtubule attachments.

    Remodeling of whole-body lipid metabolism and a diabetic-like phenotype caused by loss of CDK1 and hepatocyte division

    Jin Rong Ow, Matias J Caldez ... Philipp Kaldis
    Loss of hepatic Cdk1 leads to oxidative stress, increased fatty acids in blood, and hyperinsulinemia, which resulted in insulin resistance and hepatic steatosis, similar as in diabetes.
