CC -!- FUNCTION: Probable S-adenosyl-L-methionine-dependent methyltransferase
CC which specifically dimethylates mitochondrial 12S rRNA at the conserved
CC stem loop. In contrast to mtTFB2, it does not have a critical role in
CC either transcription or regulation of the copy number of mitochondrial
CC DNA. {ECO:0000269|PubMed:15749697}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion {ECO:0000250}.
CC -!- MISCELLANEOUS: Encoded on a bicistronic transcript that code for two
CC proteins mtTFB1 and CG42630.
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}.
