RUP response to COVID-19 crisis: Learn about the steps we are taking and find relevant content.JGP and the Society of General Physiologists have a close and long-standing collaborative relationship. Beatrice Scellini, Nicoletta Piroddi, Marica Dente, Giulia Vitale, Josè Manuel Pioner, Raffaele Coppini, Cecilia Ferrantini, Corrado Poggesi, Chiara Tesi Scellini et al. show that mavacamten, a preclinical inhibitor of sarcomeric myosins, has a fast and reversible mechanical action on skeletal and cardiac myofibers that is mediated by a shift of motor heads out of a force-generating cycle, with no effect on the kinetics of cardiac force development. David V. Rasicci, Orville Kirkland, Jr., Faruk H. Moonschi, Neil B. Wood, Danuta Szczesna-Cordary, Michael J. Previs, Jonathan F. Wenk, Kenneth S. Campbell, Christopher M. Yengo Rasicci et al. investigate the mechanochemical properties of distinct isoforms of cardiac myosin carrying the K104E regulatory light chain mutation, previously associated with hypertrophic cardiomyopathy. They demonstrate that the mutation does not affect the ATPase or motor properties of human cardiac myosin subfragment-1 (M2β-S1), but the mutation increases the sliding velocity and disrupts RLC incorporation in full-length α-cardiac myosin. Sarah R. Clippinger, Paige E. Cloonan, Wei Wang, Lina Greenberg, W. Tom Stump, Paweorn Angsutararux, Jeanne M. Nerbonne, Michael J. Greenberg Clippinger et al. examine a mutation in troponin T that causes hypertrophic cardiomyopathy and demonstrate that increased molecular mechanics drive the early disease pathogenesis, leading to secondary activation of mechanobiological signaling pathways. Acid-sensing ion channels (ASIC) play central roles in the central and peripheral nervous systems. In this paper, Chen et al. show that changes to a single arginine of a human ASIC both affect the efficacy of proton-mediated gating and delay the desensitization of the channel. Farbod Fazlollahi, Jorge J. Santini Gonzalez, Steven J. Repas, Benjamin D. Canan, George E. Billman, Paul M.L. Janssen Fazlollahi et al. show that contraction and relaxation remain tightly coupled in intact canine myocardium after exercise training and/or myocardial infarction. They postulate that the action of cardiac myosin binding protein C on actin and myosin may play a key role in this process. Mohammad-Reza Ghovanloo, Koushik Choudhury, Tagore S. Bandaru, Mohamed A. Fouda, Kaveh Rayani, Radda Rusinova, Tejas Phaterpekar, Karen Nelkenbrecher, Abeline R. Watkins, Damon Poburko, Jenifer Thewalt, Olaf S. Andersen, Lucie Delemotte, Samuel J. Goodchild, Peter C. Ruben Ghovanloo et al. combined in silico and in vitro approaches to determine the mechanism by which CBD inhibits the skeletal muscle Na+ channel Nav1.4. Their findings suggest that CBD acts directly, by binding inside the Nav1.4 pore, as well as indirectly, by modulating membrane elasticity. Chiara Stronczek, Stephan Lange, Belinda Bullard, Sebastian Wolniak, Emma Börgeson, Olga Mayans, Jennifer R. Fleming Stronczek et al. analyze the structure of the titin-N2A poly-Ig segment, a key signaling element in the sarcomere. They reveal a unique topography for the I81-I83 tandem, but they could not confirm the presence of Ca2+ binding sites in I81-I83 or the interaction of N2A with actin.Subscribe to RSS headline updates from: Powered by FeedBurner Na,K ATPases are modulated by FXYD subunits. What do the FXYDs affect, how do they do it, and what are their physiological impacts? JGP study demonstrates how recordings from neuron–HEK cell cocultures provide a clearer picture of the factors involved in synaptic transmission. Mim et al. discuss discrepancies between the known functions of pannexin 1 as an ATP and chloride channel and recently published cryo-EM structural data, which so far appear consistent only with the chloride channel function.
