    Routine single particle CryoEM sample and grid characterization by tomography

    Alex J Noble, Venkata P Dandey ... Bridget Carragher
    Fiducial-less tomography on single particle cryoEM samples reveals that most particles are adsorbed to the air-water interface and allows for researchers to diagnose and solve sample, grid, ice thickness, collection, and processing issues.

    Cell class-specific long-range axonal projections of neurons in mouse whisker-related somatosensory cortices

    Yanqi Liu, Pol Bech ... Carl CH Petersen
    Whole-brain light-sheet imaging of axons segmented by trained convolutional networks reveals distinct projection patterns of genetically defined classes of neurons in primary and secondary whisker-related somatosensory cortices.

    Mobile barrier mechanisms for Na+-coupled symport in an MFS sugar transporter

    Parameswaran Hariharan, Yuqi Shi ... Lan Guan
    The use of a conformation-selective inhibitory nanobody provides critical information on MelB at a low-sugar affinity inward-facing Na+-bound state for establishing the mobile barrier and substrate-releasing mechanisms.

    Germline VRC01 antibody recognition of a modified clade C HIV-1 envelope trimer and a glycosylated HIV-1 gp120 core

    Andrew J Borst, Connor E Weidle ... David Veesler
    An integrative structural and biophysical workflow indicates engagement of VRC01 germline antibodies can occur with a gp120 426c core construct containing all wild-type N-linked glycosylation sites, including the Asn276 glycan.

    Mechanism of pharmacochaperoning in a mammalian KATP channel revealed by cryo-EM

    Gregory M Martin, Min Woo Sung ... Show-Ling Shyng
    Diverse KATP channel inhibitors occupy a common binding pocket and stabilize an interaction between Kir6.2 and SUR1 to allosterically control gating and promote the assembly and trafficking of nascent channels.
