CC -!- FUNCTION: S-adenosyl-L-methionine-dependent methyltransferase which
CC specifically dimethylates mitochondrial 12S rRNA at the conserved stem
CC loop. Also required for basal transcription of mitochondrial DNA,
CC probably via its interaction with POLRMT and TFAM. Stimulates
CC transcription independently of the methyltransferase activity (By
CC similarity). {ECO:0000250}.
CC -!- SUBUNIT: Interacts with mitochondrial RNA polymerase POLRMT. Interacts
CC with TFAM (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC superfamily. rRNA adenine N(6)-methyltransferase family. KsgA
CC subfamily. {ECO:0000255|PROSITE-ProRule:PRU01026}.
