General annotation (Comments)
| Function | Functions in mitochondrial and peroxisomal division. Mediates membrane fission through oligomerization into ring-like structures which wrap around the scission site to constict and sever the mitochondrial membrane through a GTP hydrolysis-dependent mechanism. Required for normal brain development. Facilitates developmentally-regulated apoptosis during neural tube development. Required for a normal rate of cytochrome c release and caspase activation during apoptosis. Also required for mitochondrial fission during mitosis. Required for programmed necrosis execution. May be involved in vesicle transport By similarity. Ref.8 |
| Catalytic activity | GTP + H2O = GDP + phosphate. |
| Subunit structure | Homotetramer; dimerizes through the N-terminal GTP-middle region of one molecule binding to the GED domain of another DNM1L molecule By similarity. Can self-assemble in multimeric ring-like structures. Interacts with BCL2L1; the interaction stimulates the GTPase activity of DMN1L in synapses and increases the number of axonal mitochondria and the size and number of synaptic vesicle clusters. Interacts with FIS1. Interacts with GSK3B and MARCH5. Interacts (via the GTPase and B domains) with UBE2I; the interaction promotes sumoylation of DNM1L, mainly in ite B domain. Interacts with PPP3CA; the interaction dephosphorylates DNM1L and regulates its transition to mitochondria By similarity. Interacts with MID49 and MID51 By similarity. Interacts with PGAM5; this interaction leads to dephosphorylation at Ser-643 and activation of GTPase activity and eventually to mitochondria fragmentation By similarity. |
| Subcellular location | Cytoplasm › cytosol By similarity. Golgi apparatus By similarity. Endomembrane system; Peripheral membrane protein. Mitochondrion outer membrane; Peripheral membrane protein By similarity. Note: Mainly cytosolic. Translocated to the mitochondrial membrane through O-GlcNAcylation and interaction with FIS1. Colocalized with MARCH5 at mitochondrial membrane. Localizes to mitochondria at sites of division. Localizes to mitochondria following necrosis induction. Associated with peroxisomal membranes, partly recruited there by PEX11B. May also be associated with endoplasmic reticulum tubules and cytoplasmic vesicles and found to be perinuclear. In some cell types, localizes to the Golgi complex By similarity. |
| Tissue specificity | Expressed in the cerebellum and in several regions of the cerebrum and diencephalon. Strongly expressed in the cerebellar Purkinje cells and in the pontile giant neurons. Ref.6 |
| Domain | The GED domain folds back to interact, in cis, with the GTP-binding domain and middle domain, and interacts, in trans, with the GED domains of other DNM1L molecules, and is thus critical for activating GTPase activity and for DNM1L dimerization By similarity. |
| Post-translational modification | Phosphorylation/dephosphorylation events on two sites near the GED domain regulate mitochondrial fission. Phosphorylation on Ser-643 inhibits mitochondrial fission probably through preventing intramolecular interaction. Dephosphorylated on this site by PPP3CA which promotes mitochondrial fission. Phosphorylation on Ser-622 also promotes mitochondrial fission By similarity. Sumoylated on various lysine residues within the B domain, probably by MUL1. Sumoylation positively regulates mitochondrial fission. Desumoylated by SENP5 during G2/M transition of mitosis. Appears to be linked to its catalytic activity By similarity. S-nitrosylation increases DNM1L dimerization, mitochondrial fission and causes neuronal damage By similarity. O-GlcNAcylation augments the level of the GTP-bound active form of DRP1 and induces translocation from the cytoplasm to mitochondria in cardiomyocytes. It also decreases phosphorylation at Ser-643 By similarity. |
| Disruption phenotype | In embryonic fibroblasts, mice show defects in trophoblast giant cells and cardiomyocytes. Extensive mitochondrial networks are formed, and peroxisomes elongated. In brain, there are developmental defects in which Purkinje cells contained few giant mitochondria. In the forebrain, there is a decreased number of neurites and defective synapse formation. Embryos undergo developmentally-regulated apoptosis during neural tube formation. Mice die by around embryonic day 12. Ref.8 |
| Sequence similarities | Belongs to the dynamin family. Contains 1 GED domain. |
