    Continuous endosomes form functional subdomains and orchestrate rapid membrane trafficking in trypanosomes

    Fabian Link, Alyssa Borges ... Markus Engstler
    The endosomal apparatus of African trypanosomes consists a continuous membrane system with functional subdomains rather than distinct compartments for early, late, and recycling endosomes.

    Uni-directional ciliary membrane protein trafficking by a cytoplasmic retrograde IFT motor and ciliary ectosome shedding

    Muqing Cao, Jue Ning ... William J Snell
    During cilium-generated signaling, ciliary membrane protein trafficking is unidirectional and ciliary membrane protein composition is regulated through action in the cytoplasm of the retrograde intraflagelllar transport (IFT) motor and shedding of ciliary ectosomes.

    Genetic code expansion, click chemistry, and light-activated PI3K reveal details of membrane protein trafficking downstream of receptor tyrosine kinases

    Duk-Su Koh, Anastasiia Stratiievska ... Sharona E Gordon
    The generation of phosphoinositide 3,4,5-trisphosphate causes an increase in the number of TRPV1 ion channels and insulin receptors in the plasma membrane.

    Distinct trafficking routes of polarized and non-polarized membrane cargoes in Aspergillus nidulans

    Georgia Maria Sagia, Xenia Georgiou ... Sofia Dimou
    Unconventional secretion of a plasma membrane purine transporter via Golgi-bypass is established at an early ER-associated secretory compartment revealing that specific cargoes define alternative trafficking routes.

    High-throughput, single-particle tracking reveals nested membrane domains that dictate KRasG12D diffusion and trafficking

    Yerim Lee, Carey Phelps ... Xiaolin Nan
    The nanoscopic landscape of the membrane has a direct impact on the spatiotemporal, and likely also the signaling, dynamics of Ras proteins.

    Partitioning to ordered membrane domains regulates the kinetics of secretory traffic

    Ivan Castello-Serrano, Frederick A Heberle ... Ilya Levental
    Direct measurements of trafficking kinetics between organelles of the secretory pathway suggest that lipid-driven membrane domains laterally sort proteins during membrane traffic.

    Dynein-mediated transport and membrane trafficking control PAR3 polarised distribution

    Julie Jouette, Antoine Guichet, Sandra B Claret
    In Drosophila oocytes, the exclusion of the scaffold protein PAR3 from the posterior cortex depends on PAR1 and endocytosis, while its anterior localisation requires microtubules and recycling endosomes.

    An engineered transcriptional reporter of protein localization identifies regulators of mitochondrial and ER membrane protein trafficking in high-throughput CRISPRi screens

    Robert Coukos, David Yao ... Alice Y Ting
    HiLITR is a molecular reporter of protein localization that enables straightforward, large-scale, fluorescence-activated cell sorting-based discovery of genes that regulate complex cellular processes, such as mitochondrial and ER tail-anchored protein trafficking.

    Exocyst-mediated membrane trafficking of the lissencephaly-associated ECM receptor dystroglycan is required for proper brain compartmentalization

    Andriy S Yatsenko, Mariya M Kucherenko ... Halyna R Shcherbata
    Neuronal interacting proteome reveals that the cellular dynamics of the lissencephaly-associated extracellular matrix receptor dystroglycan are governed by the exocyst complex, which is key for proper brain assembly.

    Delivery of endocytosed proteins to the cell–division plane requires change of pathway from recycling to secretion

    Sandra Richter, Marika Kientz ... Gerd Jürgens
    The same membrane trafficking cargo can change pathways mediated by different members of ARF-GEF family of vesicle formation regulators.
