'''Dynamin''' (DNM) is a GTPase which mediates endocytosis in membrane scission<ref>PMID:22505844</ref> and organelle division.  '''Dynamin 1-like''' mediates outer mitochondrial membrane fission<ref>PMID:11703942</ref>.  DNM is a multidomain GTPase.  Mammalian genomes contain 3 DNM genes which show ca. 80% homology.  '''DNM 1''' is localized to neurons, '''DNM 2''' is expressed ubiquitously and '''DNM 3''' is found predominantly in the brain<ref>PMID:22233676</ref>.  The DNM 1 domain structure includes GTPase, middle, Plextrin homology, GTPase effector and phophotransferase regulation domains.
