    Integrative modeling reveals the molecular architecture of the intraflagellar transport A (IFT-A) complex

    Caitlyn L McCafferty, Ophelia Papoulas ... Edward M Marcotte
    The 3D structure of the six-subunit complex and its polymeric assembly gives insights into cargo transport in cilia and how specific mutations in these genes lead to ciliopathy birth defects.

    DNA-Stimulated Liquid-Liquid phase separation by eukaryotic topoisomerase ii modulates catalytic function

    Joshua Jeong, Joyce H Lee ... James M Berger
    The ability of eukaryotic topoisomerase IIs to undergo liquid-liquid phase separation is a novel process for this class of enzymes and may provide answers to many unexplained observations found in both in vitro and in vivo studies.

    Molecular basis of the PIP2-dependent regulation of CaV2.2 channel and its modulation by CaV β subunits

    Cheon-Gyu Park, Wookyung Yu, Byung-Chang Suh
    The anchoring properties of CaV β2 subunits to the plasma membrane determine the biophysical states of CaV2.2 channels by regulating PIP2 coupling to the nonspecific phospholipid-binding site in the I–II loop.

    Hepatic AMPK signaling dynamic activation in response to REDOX balance are sentinel biomarkers of exercise and antioxidant intervention to improve blood glucose control

    Meiling Wu, Anda Zhao ... Dongyun Shi
    Moderate exercise upregulated compensatory antioxidant capability and reached a high-level redox balance, whereas antioxidant intervention achieved a low-level redox balance by inhibiting oxidative stress for treating diabetes.

    Molecular mechanism of Afadin substrate recruitment to the receptor phosphatase PTPRK via its pseudophosphatase domain

    Iain M Hay, Katie E Mulholland ... Janet E Deane
    Substrate recognition by a receptor protein tyrosine phosphatase is mediated by binding to its pseudophosphatase domain via a short helix that is >100 amino acids distant from the target phosphosite, uncovering principles of phosphatase substrate recognition and potential scaffolding functions.

    Excitatory and inhibitory D-serine binding to the NMDA receptor

    Remy A Yovanno, Tsung Han Chou ... Albert Y Lau
    Molecular dynamics simulations reveal that D-serine competes with glutamate for binding to the NMDA receptor, a finding supported by electrophysiology experiments with consequences for D-serine-focused therapeutic strategies for myriad neurological disorders.

    Didemnin B and ternatin-4 differentially inhibit conformational changes in eEF1A required for aminoacyl-tRNA accommodation into mammalian ribosomes

    Manuel F Juette, Jordan D Carelli ... Scott C Blanchard
    Cyclic peptide natural products didemnin B and ternatin-4 bind the same hydrophobic pocket of eEF1A to inhibit mRNA translation but exhibit kinetic differences that influence rate-limiting conformational changes underpinning aminoacyl-tRNA selection.
