Dimethyladenosine transferase 1, mitochondrial

UniProtKB accession:  Q8JZM0

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Mitochondrial methyltransferase which uses S-adenosyl methionine to dimethylate two highly conserved adjacent adenosine residues (A1006 and A1007) within the loop of helix 45 at the 3-prime end of 12S rRNA, thereby regulating the assembly or stability of the small subunit of the mitochondrial ribosome (PubMed:19356719). 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).
