Dynamin 1-like mediates outer mitochondrial membrane fission[2]. 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[3]. The DNM 1 domain structure includes GTPase, middle, Plextrin homology, GTPase effector and phophotransferase regulation domains. Disease Mutations in DNM-2 cause centronuclear myopathy[4].
