Dynamin superfamily

Dynamin Superfamily Protein (DSP) is a protein superfamily includes classical dynamins, GBPs, Mx proteins, OPA1, mitofusins in Eukaryote, and bacterial dynamin-like proteins (BDLPs) in Prokaryote.[1] DSPs mediate eukaryotic membrane fusion and fission necessary for endocytosis, organelle biogenesis and maintenance, Mitochondrial fusion and fission, as well as for prokaryotic cytokinesis.[2]


All DSPs have two common domains: a GTPase domain and an elongated α-helical bundle domain.[2]
