RL Submitted (JUN-2004) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Mitochondrial GTPase involved in mitochondrial trafficking.
CC Probably involved in control of anterograde transport of mitochondria
CC and their subcellular distribution (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion outer membrane {ECO:0000250};
CC Single-pass type IV membrane protein {ECO:0000250}.
CC -!- PTM: Ubiquitinated by PRKN in a PINK1-dependent manner, leading to its
CC degradation. {ECO:0000250|UniProtKB:Q8IXI1}.
CC -!- SIMILARITY: Belongs to the mitochondrial Rho GTPase family.
CC {ECO:0000255|PROSITE-ProRule:PRU00757, ECO:0000305}.
