Mitochondrial GTPase involved in mitochondrial trafficking ( ). Probably involved in control of anterograde transport of mitochondria and their subcellular distribution ( ). Promotes mitochondrial fission during high calcium conditions .
Subcellular locations: Mitochondrion outer membrane
Colocalizes with MGARP and RHOT2 at the mitochondria.
Ubiquitously expressed. Expressed at high level in heart and skeletal muscle.
