Dynamin is a protein that catalyses the scission of clathrin-coated pits at the plasma membrane. The mechanisms of dynamin-catalysed scission remain poorly understood. Here, the structure of the stalk region of human MxA, a dynamin-like protein, is presented. A structural model of MxA oligomerization and stimulated GTP hydrolysis is put forward that has functional implications for all members of the dynamin family.
