Also known as: DRP1
Summary: Enables GTPase activity and identical protein binding activity. Involved in several processes, including heme transport; mitochondrion inheritance; and organelle fission. Acts upstream of or within intracellular distribution of mitochondria and membrane bending. Located in cytosol; mitochondrial outer membrane; and peroxisome. Is active in mitochondrion. Used to study encephalopathy due to defective mitochondrial and peroxisomal fission 1. 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).
