Summary: Enables GTPase activity and identical protein binding activity. Involved in several processes, including heme transport; mitochondrion organization; and peroxisome fission. Located in cytosol; mitochondrial outer membrane; and peroxisome. 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).
