    Sec17/Sec18 act twice, enhancing membrane fusion and then disassembling cis-SNARE complexes

    Hongki Song et al.
    Sec17 (αSNAP) and Sec18 (NSF) are shown to act twice, to promote fusion per se and to recycle SNAREs after fusion.

    The splicing regulator PTBP2 controls a program of embryonic splicing required for neuronal maturation

    Qin Li et al.
    PTBP2 ensures that adult protein variants are expressed only in mature neurons through regulation of alternative splicing during early neuronal development.

    Multiplex image-based autophagy RNAi screening identifies SMCR8 as ULK1 kinase activity and gene expression regulator

    Jennifer Jung et al.
    An image-based multiplex autophagosome RNAi screen targeting all Rab GTPases as well as their GAPs and GEFs identifies the Rab GEF SMCR8 as multifaceted autophagy modulator, which regulates kinase activity and gene expression of ULK1.

    Inhibition of Transient Receptor Potential Melastatin 3 ion channels by G-protein βγ subunits

    Doreen Badheka et al.
    Electrophysiological experiments, Ca2+ imaging, and behavioral studies in mice identify the TRPM3 ion channel as a novel target of G-protein βγ subunits.

    CHIP as a membrane-shuttling proteostasis sensor

    Yannick Kopp et al.
    The mechanism is revealed that connects the protein degradation machinery to cellular membrane-bound compartments during proteostasis stress in mammalian cells.

    Myotubularin related protein-2 and its phospholipid substrate PIP2 control Piezo2-mediated mechanotransduction in peripheral sensory neurons

    Pratibha Narayanan et al.
    Local Mtmr2 activity and PI(3,5)P2 abundance dynamically control Piezo2-dependent mechanotransduction in peripheral sensory neurons.

    Molecular mechanism to target the endosomal Mon1-Ccz1 GEF complex to the pre-autophagosomal structure

    Jieqiong Gao et al.
    The endosomal GEF Mon1-Ccz1 binds to Atg8 on autophagosomes, and recruits its substrate, the Rab7-like Ypt7, which then mediates fusion of the autophagosomes with the lysosome.

    Uncoupling of dynamin polymerization and GTPase activity revealed by the conformation-specific nanobody dynab

    Valentina Galli et al.
    Uncoupling of dynamin polymerization and GTPase activity can be induced with dynamin, which allows in vivo visualization of its activity at endocytic pits.

    Cation selectivity of the presequence translocase channel Tim23 is crucial for efficient protein import

    Niels Denkert et al.
    Channel characteristics of the presequence translocation pore have a direct impact on protein import into the mitochondrial matrix.

    Genetic screen in Drosophila muscle identifies autophagy-mediated T-tubule remodeling and a Rab2 role in autophagy

    Naonobu Fujita et al.
    Analyses of a developmentally regulated Drosophila myofiber remodeling program provide insight into induced autophagy required for T-tubule membrane reorganization, and uncover a conserved Rab2 role in autophagosome-lysosome fusion.
