    GABAB receptor auxiliary subunits modulate Cav2.3-mediated release from medial habenula terminals

    Pradeep Bhandari et al.
    The direct interaction of R-type Ca2+ channel Cav2.3 and GABAB receptor auxiliary subunits in the active zone of medial habenula terminals scales synaptic strength independent of GABAB receptor activation.

    Permeabilization-free en bloc immunohistochemistry for correlative microscopy

    Kara A Fulton, Kevin L Briggman
    Immunohistochemical labeling of antigens deep within mouse brain tissue sections was achieved without the need for lipid permeabilization, thereby preserving tissue ultrastructure and enabling correlative light and electron microscopy studies.

    Membrane transporter dimerization driven by differential lipid solvation energetics of dissociated and associated states

    Rahul Chadda et al.
    Differences in the lipid solvation energetics of associated and dissociated states is a primary driving force for membrane protein oligomerization, presenting a molecular mechanism for lipid regulation in biology.

    The final step of 40S ribosomal subunit maturation is controlled by a dual key lock

    Laura Plassart et al.
    Cryo-EM and functional studies reveal how combined action of proteins RPS26/eS26 and RIO1 allows late precursors to the human small ribosomal particle to be matured into fully translation-competent 40S subunits.

    Structural determinants of voltage-gating properties in calcium channels

    Monica L Fernández-Quintero et al.
    Structure modeling, site-directed mutagenesis, and current recordings revealed the mechanism by which stabilization of voltage sensors in the resting and activated states determines the gating properties of the CaV1.1 calcium channel.
