CC -!- FUNCTION: Mitochondrial GTPase involved in mitochondrial trafficking
CC (By similarity). Probably involved in control of anterograde transport
CC of mitochondria and their subcellular distribution (By similarity).
CC Plays a role in maintaining mitochondrial morphology (PubMed:25190516).
CC {ECO:0000250|UniProtKB:Q8IXI2, ECO:0000269|PubMed:25190516}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion outer membrane
CC {ECO:0000250|UniProtKB:Q8IXI2}; Single-pass type IV membrane protein
CC {ECO:0000255}.
CC -!- DISRUPTION PHENOTYPE: RNAi-mediated knockdown results in a hyper-
CC connected mitochondrial network in body wall muscle cells.
CC {ECO:0000269|PubMed:25190516}.
CC -!- SIMILARITY: Belongs to the mitochondrial Rho GTPase family.
CC {ECO:0000305}.
