WebDynamin, best studied for its role in clathrin-mediated endocytosis, is the prototypical member of a family of multidomain GTPases involved in fission and remodeling of multiple organelles. Recent studies have shown that dynamin alone can catalyze fission of membrane tubules and vesicle formation from planar lipid templates. WebApr 13, 2024 · In eukaryotes, dynamins and dynamin-related proteins (DRPs) are high–molecular weight GTPases responsible for mechanochemical fission of organelles or membranes. Of the six DRP subfamilies in Arabidopsis thaliana, AtDRP1 and AtDRP2 family members serve as endocytic accessory proteins in clathrin-mediated endocytosis. Most …

WebThe clathrin-coated pits are separated from the membrane by a process called fission. As lipid bilayers are auto-sealable, fission is not a spontaneous event. This important step … Webmembrane fission.
