Template:Short description Template:Infobox gene Dimethyladenosine transferase 1, mitochondrial; Transcription factor B1, mitochondrial is a mitochondrial enzyme that is encoded by the TFB1M gene.[1][2][3]

TFB1M is a mitochondrial methyltransferase, which uses S-adenosyl methionine to dimethylate two highly conserved adenosine residues at the 3'-end of the mitochondrial 12S rRNA thereby regulating the assembly or stability of the small subunit of the mitochondrial ribosome.[2][4][5]

Additionally, TFB1M has been demonstrated to stimulate transcription from promoter templates in an in vitro system containing recombinant mitochondrial RNA polymerase and TFAM.[6] There are no experimental data demonstrating that this function occurs in vivo; the paralogous TFB2M is more specific for this role.[7]

Interactions

TFB1M has been shown to interact with TFAM.[8]
