== Function Summary ==
* **Entrez Summary**: The protein encoded by this gene is involved in the translocation of cobalamin into the mitochondrion, where it is used in the final steps of adenosylcobalamin synthesis. Adenosylcobalamin is a coenzyme required for the activity of methylmalonyl-CoA mutase. Defects in this gene are a cause of methylmalonic aciduria. [provided by RefSeq, Jul 2008].
* **UniProt Summary**: GTPase, binds and hydrolyzes GTP (PubMed:28497574, PubMed:20876572). Involved in intracellular vitamin B12 metabolism, mediates the transport of cobalamin (Cbl) into mitochondria for the final steps of adenosylcobalamin (AdoCbl) synthesis. Functions as a G-protein chaperone that assists AdoCbl cofactor delivery from MMAB to the methylmalonyl-CoA mutase (MUT) and reactivation of the enzyme during catalysis (PubMed:28497574, PubMed:20876572). {ECO:0000269|PubMed:20876572, ECO:0000269|PubMed:28497574}.
