    An unmet actin requirement explains the mitotic inhibition of clathrin-mediated endocytosis

    Satdip Kaur, Andrew B Fielding ... Stephen J Royle
    Endocytosis is switched off in dividing cells because actin is not available to assist the clathrin machinery at a time when membrane tension is increased.

    Evolutionarily unique mechanistic framework of clathrin-mediated endocytosis in plants

    Madhumitha Narasimhan, Alexander Johnson ... Jiří Friml
    The examination of the ultra-structure and in vivo dynamics of endocytosis in plants reveal plants unique actin-independent, clathrin-mediated endocytosis mechanisms to overcome their unique physiological properties.

    Single-molecule turnover dynamics of actin and membrane coat proteins in clathrin-mediated endocytosis

    Michael M Lacy, David Baddeley, Julien Berro
    The main proteins of clathrin-mediated endocytosis bind and unbind rapidly, continuously turning over about five times during the formation of an endocytic vesicle in yeast.

    Principles of self-organization and load adaptation by the actin cytoskeleton during clathrin-mediated endocytosis

    Matthew Akamatsu, Ritvik Vasan ... David G Drubin
    An experimentally constrained multiscale mathematical model predicts that branched actin networks self-organize at endocytic sites and bend to produce force, which was verified with cryo-electron tomography of intact cells.

    A dynamin 1-, dynamin 3- and clathrin-independent pathway of synaptic vesicle recycling mediated by bulk endocytosis

    Yumei Wu, Eileen T O'Toole ... Pietro De Camilli
    Analysis of neurons that lack the two neuronal dynamins, dynamin 1 and 3, demonstrates a pathway of synaptic vesicle reformation that does not require these two dynamins or clathrin-dependent budding.

    Direct comparison of clathrin-mediated endocytosis in budding and fission yeast reveals conserved and evolvable features

    Yidi Sun, Johannes Schöneberg ... David G Drubin
    Quantitative comparison of clathrin-mediated endocytosis in budding and fission yeast identified conserved mechanisms and species-specific adaptations with broad implications that extend from yeast to humans.

    Distinct modes of endocytotic presynaptic membrane and protein uptake at the calyx of Held terminal of rats and mice

    Yuji Okamoto, Noa Lipstein ... Mitsuharu Midorikawa
    Capacitance measurements and pH imaging reveal distinct modes of uptake for endocytotic presynaptic membrane and proteins.

    Clathrin-independent endocytic retrieval of SV proteins mediated by the clathrin adaptor AP-2 at mammalian central synapses

    Tania López-Hernández, Koh-ichiro Takenaka ... Shigeo Takamori
    At mammalian synapses the clathrin adaptor AP-2 plays a crucial role in the endocytic retrieval of a subset of synaptic vesicle proteins from the presynaptic cell surface, while clathrin is dispensable.

    A role of OCRL in clathrin-coated pit dynamics and uncoating revealed by studies of Lowe syndrome cells

    Ramiro Nández, Daniel M Balkin ... Pietro De Camilli
    Studies of Lowe syndrome patient cells, which lack the inositol 5-phosphatase OCRL, suggest that a defect in endocytosis plays a role in the pathological manifestations of the disease.

    Epsin deficiency impairs endocytosis by stalling the actin-dependent invagination of endocytic clathrin-coated pits

    Mirko Messa, Rubén Fernández-Busnadiego ... Pietro De Camilli
    Epsin has a key role in the coupling of actin to endocytic clathrin coated pits that is required for their maturation and helps capture SNAREs at endocytic clathrin coated pits.
