Dimethyladenosine transferase 1, mitochondrial; Transcription factor B1, mitochondrial is a mitochondrial enzyme that in humans is encoded by the TFB1M gene.[5][6][7] 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.[6][8][9]

Additionally, TFB1M has been demonstrated to stimulate transcription from promoter templates in an in vitro system containing recombinant mitochondrial RNA polymerase and TFAM.[10] There are no experimental data demonstrating that this function occurs in vivo.

Interactions

TFB1M has been shown to interact with TFAM.[11]
