GeneCards Summary for TFB2M Gene

TFB2M (Transcription Factor B2, Mitochondrial) is a Protein Coding gene. Diseases associated with TFB2M include hepatitis c virus and hepatitis c. Among its related pathways are Gene Expression and RNA Polymerase I Promoter Opening. GO annotations related to this gene include transcription cofactor activity and rRNA (adenine-N6,N6-)-dimethyltransferase activity.

UniProtKB/Swiss-Prot for TFB2M Gene

  • 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. Compared to TFB1M, it activates transcription of mitochondrial DNA more efficiently, while it has less methyltransferase activity.
