Squeeze pumping of lipids and insecticides by ABCH transporter High-resolution cryo-EM structures and biochemical data reveal the dynamic process by which the ABCH transporter binds and transports lipid substrates and insecticides across cell membranes while detoxifying insecticides, providing atomic-level insights for the development of arthropod pest control agents and strategies for managing pesticide resistance.

Ion coupling and inhibitory mechanisms of the human presynaptic high-affinity choline transporter CHT1 | Structure

Ion coupling and inhibitory mechanisms of the human presynaptic high-affinity choline transporter CHT1 Qiu et al. report the cryo-EM structures of the human high-affinity choline transporter 1 (CHT1) with bound inhibitors, the substrate choline, and a substrate-free state. These structures reveal the binding modes of inhibitors with different chemical structures and shed light on the ion-coupled substrate transport mechanism of CHT1.

Architecture of the high-affinity immunoglobulin E receptor Structural analysis reveals species-specific differences in how the antibody IgE binds to its receptor FcεRI.

By solving the cryo-EM structures of human and mouse FcεRI bound to IgE-Fc, Zhang et al. found species-specific differences in interactions between IgE and the extracellular domains of the receptors.

GABAA receptor π forms channels that stimulate ERK through a G-protein-dependent pathway GABAA receptor π (GABRP) can form homopentameric channel-like structures, similar to the more common heteromeric type-A GABA receptor channels. However, GABRP activation by GABA uniquely induces a G-protein-signaling pathway rather than allowing chloride passage. Selective inhibition of GABRP signaling may hold therapeutic promise for GABRP-associated cancers.

Insights into the distinct membrane targeting mechanisms of WDR91 family proteins Proteins from the WDR91 family control phosphoinositide conversion required for endosome maturation. By combining structural, biochemical, and cellular data, Ma et al. provide evidence that two representative members of this family WDR91 and SORF1 either use the Rab7-binding WD40 domain or an amphipathic helix for membrane targeting.
