CC -!- FUNCTION: High-conductance magnesium-selective channel that CC mediates the influx of magnesium into the mitochondrial matrix. CC Essential for the splicing of mRNA group II introns in CC mitochondria by affecting mitochondrial magnesium concentrations, CC which are critical for group II intron splicing. It also CC suppresses a variety of mitochondrial intron mutations and its CC absence may disturb the assembly of mitochondrial membrane CC 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) CC (TC 1.A.35) family. {ECO:0000305}.
