Dynamin superfamily proteins comprising classical dynamins and related proteins are membrane remodelling agentsinvolved in several biological processes such as endocytosis, maintenance of organelle morphology and viralresistance. These large GTPases couple GTP hydrolysis with membrane alterations such as fission, fusion ortubulation by undergoing repeated cycles of self-assembly/disassembly. The functions of these proteins are regulatedby various post-translational modifications that affect their GTPase activity, multimerization or membrane association.Recently, several reports have demonstrated variety of such modifications providing a better understanding of themechanisms by which dynamin proteins influence cellular responses to physiological and environmental cues. In thisreview, we discuss major post-translational modifications along with their roles in the mechanism of dynaminfunctions and implications in various cellular processes.
