Abstract

Endocytic vesicle formation is a complex process that couples sequential protein recruitment and lipid modifications with dramatic shape transformations of the plasma membrane. Although individual molecular players have been studied intensively, how they all fit into a coherent picture of endocytosis remains unclear. That is, how the proper temporal and spatial coordination of endocytic events is achieved and what drives vesicle scission are not known. Drawing upon detailed knowledge from experiments in yeast, we develop the first integrated mechanochemical model that quantitatively recapitulates the temporal and spatial progression of endocytic events leading to vesicle scission. The central idea is that membrane curvature is coupled to the accompanying biochemical reactions. This coupling ensures that the process is robust and culminates in an interfacial force that pinches off the vesicle. Calculated phase diagrams reproduce endocytic mutant phenotypes observed in experiments and predict unique testable endocytic phenotypes in yeast and mammalian cells. The combination of experiments and theory in this work suggest a unified mechanism for endocytic vesicle formation across eukaryotes.

  • Endocytic proteins such as Synaptojanin 1, Endophilin A, Syndapin 1, and Dynamin 1 can further curve the membrane and generate vesicles.

    “Thereafter, endocytic proteins such as Synaptojanin 1, Endophilin A, Syndapin 1, and Dynamin 1 can further curve the membrane and generate vesicles47–50.”

    The Introduction says BAR-domain proteins can deform membranes, and the Results link yeast synaptojanin’s PIP2 hydrolysis to vesicle scission. The Introduction also describes dynamin GTPases as proposed to constrict membrane tubules. Our copy does not establish the claimed membrane-curving and vesicle-generating roles for all four named proteins, particularly Syndapin 1; much of the model concerns yeast proteins rather than the specific proteins listed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
