Summary: Predicted to enable GTPase activity and microtubule binding activity. Involved in several processes, including mitochondrion organization; positive regulation of mitochondrial fission; and ventral furrow formation. Located in mitochondrion. Is expressed in adult head. Human ortholog(s) of this gene implicated in encephalopathy due to defective mitochondrial and peroxisomal fission 1 and optic atrophy 5. Orthologous to human DNM1L (dynamin 1 like).
