Membrane fission articles from across Nature Portfolio

It is estimated that about 80% of endocytosed material is recycled back to the plasma membrane. Here, the authors show that kiss-and-run of Rab5 early endocytic and Rab11 recycling vesicles on sorting endosomes allow cargo flow, providing more robustness and fidelity to the sorting process.

Dynamin mediates the fission of vesicles during endocytosis. Here, the authors report the cryoEM structure of a super-constricted two-start dynamin 1 filament- one of the two known helical forms of dynamin, with insights into the molecular mechanisms of dynamin-mediated membrane scission.

Membrane contact sites between organelles have specialized functions that are only beginning to be understood. Here, the authors show that ORP1L mediates lysosome recruitment and PI(4)P signaling at endoplasmic reticulum-lysosome-mitochondria three-way contact sites involved in mitochondrial division.

Salmonella secretes the effector protein SopD into the host cell cytoplasm, leading to scission of the plasma membrane through unclear mechanisms. Here, Boddy et al. show that SopD binds to and inhibits the small GTPase Rab10, thus promoting removal of Rab10 and recruitment of dynamin-2 to drive plasma membrane scission.

Gong et al. uncover a role for the Golgi network in ER-associated endosome fission, showing that a Golgi-derived SEC14L2 compartment mediates ER-associated endosome fission by promoting PtdIns4P to PtdIns3P conversion.

Endocytosis mediates the cellular uptake of micronutrients and cell surface proteins. Here, the authors show that Cdk5 and GSK3β are negative regulators of fast Endophilin-mediated endocytosis (FEME).
