Abstract

Dynamin is a multidomain mechanochemical guanine triphosphatase that catalyzes membrane scission, most notably of clathrin-coated endocytic vesicles. A number of recent publications have provided structural and mechanistic insights into the formation of helical dynamin filaments assembled by dynamic interactions of multiple domains within dynamin. As a prerequisite for membrane scission, this oligomer undergoes nucleotide-triggered large scale dynamic rearrangements. Here, we review these structural findings and discuss how the architecture of dynamin is poised for the assembly into right-handed helical filaments. Based on these data, we propose a structure-based model for dynamin-mediated scission of membranes.
