Abstract

During clathrin-mediated endocytosis, membrane scission marks the isolation of a cargo-laden clathrin-coated pit (CCP) from the cell exterior. Here we used live-cell imaging of a pH-sensitive cargo to visualize the formation of clathrin-coated vesicles (CCVs) at single CCPs with a time resolution of seconds. We show that CCPs are highly dynamic and can produce multiple vesicles in succession. Using alternating evanescent field and epifluorescence illumination, we show that CCP invagination and scission are tightly coupled, with scission coinciding with maximal displacement of CCPs from the plasma membrane and with peak recruitment of cortactin-DsRed, a dynamin and F-actin binding protein. Finally, perturbing actin polymerization with latrunculin-B drastically reduces the efficiency of membrane scission and affects many aspects of CCP dynamics. We propose that CCP invagination, actin polymerization, and CCV formation are highly coordinated for efficient endocytosis.

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.
