Atypical mitochondrial nucleoside-triphosphatase (NTPase) involved in mitochondrial trafficking (PubMed:16630562, PubMed:22396657, PubMed:30513825). Probably involved in control of anterograde transport of mitochondria and their subcellular distribution (PubMed:22396657). Can hydrolyze GTP (By similarity). Can hydrolyze ATP and UTP (PubMed:30513825). {ECO:0000250|UniProtKB:Q8IXI2, ECO:0000269|PubMed:16630562, ECO:0000269|PubMed:22396657, ECO:0000269|PubMed:30513825}. This is the function of Ensembl gene identifier ENSG00000140983 (RHOT2, ras homolog family member T2).
