RT   magnesium exporter.";
RL   Biochim. Biophys. Acta 1853:724-732(2015).
CC   -!- FUNCTION: Transporter of the mitochondrial inner membrane that exports
CC       magnesium and thus, plays a key role in mitochondrial Mg(2+)
CC       homeostasis. {ECO:0000269|PubMed:25585246,
CC       ECO:0000305|PubMed:10930523}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC       {ECO:0000269|PubMed:25585246}; Multi-pass membrane protein
CC       {ECO:0000255}.
CC   -!- DISRUPTION PHENOTYPE: Significantly increases steady-state
CC       mitochondrial magnesium concentration (PubMed:25585246). Rescues the
CC       group II RNA splicing defect in the MRS2 and LPE10 deletion mutants
CC       (PubMed:25585246). {ECO:0000269|PubMed:25585246}.
CC   -!- MISCELLANEOUS: Present with 2060 molecules/cell in log phase SD medium.
CC       {ECO:0000269|PubMed:14562106}.
CC   -!- SIMILARITY: Belongs to the mitochondrial carrier (TC 2.A.29) family.
CC       {ECO:0000305}.
