Summaries for TFB1M Gene

Entrez Gene Summary for TFB1M Gene

  • The protein encoded by this gene is a dimethyltransferase that methylates the conserved stem loop of mitochondrial 12S rRNA. The encoded protein also is part of the basal mitochondrial transcription complex and is necessary for mitochondrial gene expression. The methylation and transcriptional activities of this protein are independent of one another. Variations in this gene may influence the severity of aminoglycoside-induced deafness (AID).[provided by RefSeq, Aug 2010]

GeneCards Summary for TFB1M Gene

TFB1M (Transcription Factor B1, Mitochondrial) is a Protein Coding gene. Diseases associated with TFB1M include mitochondrial non-syndromic sensorineural deafness. Among its related pathways are Energy Metabolism and Mitochondrial Gene Expression. GO annotations related to this gene include rRNA (adenine-N6,N6-)-dimethyltransferase activity. An important paralog of this gene is DIMT1.

UniProtKB/Swiss-Prot for TFB1M 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.
