| malfunction | dynamin gene mutations are responsible for the temperature-sensitive paralytic phenotype of Drosophila melanogaster shibire mutants. The mutants show paralysis resulting from the neuronal activity-dependent depletion of synaptic vesicles, which is accompanied by the accumulation of arrested collared endocytic pits at the presynaptic plasma membrane | Drosophila melanogaster |
| malfunction | dynamin mutants with impaired GTP binding and/or hydrolysis cycles have dominant-negative effects on endocytosis. Also PH-domain mutants that impair phosphoinositide binding exert dominant-negative effects on clathrin-mediated endocytosis. Dynamin lacking the PRD cannot rescue endocytic defects in dynamin-knockout fibroblasts | Mus musculus |

| physiological function | dynamin drives membrane fission, mechanism, overview. Dynamin is directly involved in the generation of an endocytic vesicle requiring the recruitment of various proteins from the cytosol that orchestrate the bending inward of the plasma membrane to form a deeply invaginated bud and subsequently promote its fission. Dynamin assembles into helical polymers at the necks of budding vesicles and its GTP hydrolysis-dependent conformational change promotes fission of the underlying tubular membrane to generate a free endocytic vesicle. It acts at fission sites for clathrin-mediated endocytosis. Diverse roles for dynamin-like proteins at membrane interfaces, overview. Dynamin is also implicated in some clathrin-independent endocytic pathways, overview. Dynamin affects signalling. Dynamin participates in synaptic vesicle recycling at neuronal synapses. Dynamin interacts both directly and indirectly with the cytoskeleton, overview. Dynamin 2 concentrates at sites of abscission and is implicated in the completion of cytokinesis | Mus musculus |
