Function

Mitochondrial GTPase involved in mitochondrial trafficking. Probably involved in control of anterograde transport of mitochondria and their subcellular distribution (By similarity). {ECO:0000250}.

Subcellular Localization

Mitochondrion outer membrane {ECO:0000269PubMed:12482879, ECO:0000269PubMed:19528298}; Single-pass type IV membrane protein {ECO:0000269PubMed:12482879, ECO:0000269PubMed:19528298}. Note=Colocalizes with MGARP and RHOT2 at the mitochondria.

Disease Associations

Tissue Specificity

Ubiquitously expressed. Highly expressed in heart, liver, skeletal muscle, kidney and pancreas. {ECO:0000269PubMed:12482879, ECO:0000269PubMed:15218247}.
