Protein: Dimethyladenosine transferase 1, mitochondrial (Q8JZM0)
Organism: Mus musculus (Mouse)
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 (By similarity)
Subcellular location: Mitochondrion
InterPro domains:
- IPR023165: rRNA adenine dimethylase-like, C-terminal (homologous_superfamily) [239-328]
- IPR020596: Ribosomal RNA adenine methylase transferase, conserved site (conserved_site) [59-87]
- IPR011530: Ribosomal RNA adenine dimethylase (family) [27-308]
- IPR029063: S-adenosyl-L-methionine-dependent methyltransferase superfamily (homologous_superfamily) [2-310]
- IPR001737: Ribosomal RNA adenine methyltransferase KsgA/Erm (family) [11-313]
- IPR020598: Ribosomal RNA adenine methylase transferase, N-terminal (domain) [43-234]
