The dynamin superfamily comprises a growing assortment of multi-domain GTPases, found from bacteria to man, that are distinguished from typical GTPases of the Ras, Rab and G-protein families by their modular structure (Figure 1), relatively large size (>70 kDa), and low affinity for guanine nucleotides. In addition, they display a conserved propensity to self-assemble into polymeric arrays, the dynamics of which are regulated by an autonomous, assembly-stimulated GTPase activity. Here, Ramachandran and Schmid describe the structural, biophysical, and biochemical properties of the dynamin superfamily and the implications for their distinct cellular functions.
