功能： function:S-adenosyl-L-methionine-dependent methyltransferase which specifically dimethylates mitochondrial 12S rRNA at the conserved stem loop. Also required for basal transcription of mitochondrial DNA, probably via its interaction with POLRMT and TFAM. Stimulates transcription independently of the methyltransferase activity. Compared to TFB1M, it activates transcription of mitochondrial DNA more efficiently, while it has less methyltransferase activity.,induction:By the nuclear respiratory factors NRF1 and NRF2/GABPB2 and PGC-1 coactivators.,similarity:Belongs to the rRNA adenine N(6)-methyltransferase family. KsgA subfamily.,subunit:Interacts with mitochondrial RNA polymerase POLRMT. Interacts with TFAM.,tissue specificity:Ubiquitously expressed.,
