Mitochondrial GTPase involved in mitochondrial trafficking (By similarity). Probably involved in control of anterograde transport of mitochondria and their subcellular distribution (By similarity). Plays a role in maintaining mitochondrial morphology (PubMed:25190516). RNAi-mediated knockdown results in a hyper-connected mitochondrial network in body wall muscle cells. Belongs to the mitochondrial Rho GTPase family.
