UniProtKB - Q2PG46 (TFB1M_MACFA)
Protein
Dimethyladenosine transferase 1, mitochondrial
Gene
TFB1M
Organism
Macaca fascicularis (Crab-eating macaque) (Cynomolgus monkey)
Status
Functioni
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 (By similarity).By similarity
