CC   -!- FUNCTION: High-conductance magnesium-selective channel that mediates
CC       the influx of magnesium into the mitochondrial matrix. Essential for
CC       the splicing of mRNA group II introns in mitochondria by affecting
CC       mitochondrial magnesium concentrations, which are critical for group II
CC       intron splicing. It also suppresses a variety of mitochondrial intron
CC       mutations and its absence may disturb the assembly of mitochondrial
CC       membrane complexes. {ECO:0000250|UniProtKB:Q01926}.
CC   -!- SUBUNIT: Homopentamer. Forms homooligomers. Interacts with MFM1.
CC       {ECO:0000250|UniProtKB:Q01926}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC       {ECO:0000250|UniProtKB:Q01926}; Multi-pass membrane protein
CC       {ECO:0000250|UniProtKB:Q01926}.
CC   -!- SIMILARITY: Belongs to the CorA metal ion transporter (MIT) (TC 1.A.35)
CC       family. {ECO:0000305}.
