Dynamin 1-like mediates outer mitochondrial membrane fission. 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. The DNM 1 domain structure includes GTPase, middle, Plextrin homology, GTPase effector and proline- and arginine-rich (PRD) domains. Disease Mutations in DNM-2 cause centronuclear myopathy. Structural highlights The GTPase domain of DNM 1 contains several nucleotide binding motifs which interact with the bound GDP. Motif GGQSAGKS residues 38-45; Motif TKLD residues 205-208; Motif NRSQKDIDGKK reidues 236-246. Water molecules are shown as red spheres. Whole binding site.
