The function of dynamin in endocytosis.
Temperature-sensitive shibire mutants of Drosophila melanogaster become rapidly paralyzed upon a shift to the restrictive temperature, which is due to a block in synaptic vesicle endocytosis. The shibire gene encodes the GTPase dynamin. Recent studies have shown that dynamin forms rings at the neck of invaginated clathrin-coated pits, and have suggested that a conformational change in the ring, which correlates with GTP hydrolysis, plays an essential role in vesicle fission.
