General annotation (Comments)
| Function | Functions in mitochondrial and peroxisomal division probably by regulating membrane fission. Enzyme hydrolyzing GTP that oligomerizes to form ring-like structures and is able to remodel membranes. May also play a role on organelles of the secretory pathway. Ref.6 Ref.7 |
| Catalytic activity | GTP + H2O = GDP + phosphate. |
| Subunit structure | Homotetramer; N-terminal part binds to the C-terminal part of another DNM1L. Can self-assemble in multimeric ring-like structures. Interacts with GSK3B and FIS1. Ref.7 Ref.2 Ref.5 |
| Subcellular location | Cytoplasm › cytosol By similarity. Endomembrane system; Peripheral membrane protein By similarity. Note: Mainly cytosolic By similarity. Also membrane-associated. Localizes to mitochondria at spots of division events. Associated with peroxisomal membranes, it is recruited in part by PEX11B. May also be associated with endoplasmic reticulum tubules and cytoplasmic vesicles and found to be perinuclear By similarity. |
| Tissue specificity | Expressed in all tissues tested (at protein level). Longer isoforms are preferentially expressed in brain. Ref.2 Ref.1 |
| Induction | By bezafibrate. Ref.6 |
| Post-translational modification | Phosphorylated by GSK3B. Ref.2 |
| Sequence similarities | Belongs to the dynamin family. Contains 1 GED domain. |
