    Modulation of biophysical properties of nucleocapsid protein in the mutant spectrum of SARS-CoV-2

    Ai Nguyen, Huaying Zhao ... Peter Schuck
    Exploration of the phenotype space corresponding to the sequence space of viable SARS-CoV-2 nucleocapsid protein species reveals significant diversity of biophysical characteristics, nonlocal mutation effects, and functional constraints.

    Gradients in the biophysical properties of neonatal auditory neurons align with synaptic contact position and the intensity coding map of inner hair cells

    Alexander L Markowitz, Radha Kalluri
    The biophysical diversity that is intrinsic to spiral ganglion neurons emerges as spatial gradients during early post-natal development and endures through subsequent maturation to likely contribute to sound intensity coding.

    Neto auxiliary proteins control both the trafficking and biophysical properties of the kainate receptor GluK1

    Nengyin Sheng, Yun S Shi ... Roger A Nicoll
    Auxiliary subunits Neto1 and Neto2 regulate the GluK1 receptor targeting to excitatory silent synapses through different molecular mechanisms and also modify receptor biophysics through distinct mechanisms.

    Systematic analysis of the molecular and biophysical properties of key DNA damage response factors

    Joshua R Heyza, Mariia Mikhova ... Jens C Schmidt
    Live-cell single-molecule imaging of DNA repair factors can be used to analyze their localization to DNA lesions and dissect the hierarchy of their recruitment.

    Biophysical properties of single rotavirus particles account for the functions of protein shells in a multilayered virus

    Manuel Jiménez-Zaragoza, Marina PL Yubero ... Javier M Rodríguez
    In triple-layered rotavirus particles, strong interaction between the external and middle layers provides high mechanical strength for protection tasks, while weaker interaction between the middle and inner layers favors transcription.

    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.
