    Preferential assembly of heteromeric kainate and AMPA receptor amino terminal domains

    Huaying Zhao, Suvendu Lomash ... Peter Schuck
    Members of kainate and AMPA families of glutamate receptors exhibit large differences in affinity for homo- and hetero-dimerziation of their amino terminal domains, which may control gating characteristics and ion selectivity of receptor subtypes with different subunit composition.

    Dynamics of the IFT machinery at the ciliary tip

    Alexander Chien, Sheng Min Shih ... Ahmet Yildiz
    During intraflagellar transport (IFT), kinesin-II dissociates from IFT trains at the flagellar tip and its diffusion in flagella serves as a negative feedback mechanism that facilitates flagellar length control in Chlamydomonas.

    Anti-diabetic drug binding site in a mammalian KATP channel revealed by Cryo-EM

    Gregory M Martin, Balamurugan Kandasamy ... Show-Ling Shyng
    A structure of a pancreatic ATP-sensitive potassium channel complex at 3.63Å resolution obtained by cryo-electron microscopy reveals how a commonly used anti-diabetic drug interacts with and inhibits the channel to stimulate insulin secretion.

    Patient-specific mutations impair BESTROPHIN1’s essential role in mediating Ca2+-dependent Cl- currents in human RPE

    Yao Li, Yu Zhang ... Tingting Yang
    A multidisciplinary platform featured by patient-derived RPEs is established to study the disease-causing mechanisms of BEST1 mutations, and demonstrates gene-supplemented rescue of the mutation-caused deficiency in Ca2+-dependent Cl- current in human RPE.
