Anti-mtTFA antibody - Mitochondrial Marker,Abcam,AB272885

Target data Binds to the mitochondrial light strand promoter and functions in mitochondrial transcription regulation (PubMed : 29445193, PubMed : 32183942). Component of the mitochondrial transcription initiation complex, composed at least of TFB2M, TFAM and POLRMT that is required for basal transcription of mitochondrial DNA (PubMed : 29149603). In this complex, TFAM recruits POLRMT to a specific promoter whereas TFB2M induces structural changes in POLRMT to enable promoter opening and trapping of the DNA non-template strand (PubMed : 20410300). Required for accurate and efficient promoter recognition by the mitochondrial RNA polymerase (PubMed : 22037172). Promotes transcription initiation from the HSP1 and the light strand promoter by binding immediately upstream of transcriptional start sites (PubMed : 22037172). Is able to unwind DNA (PubMed : 22037172). Bends the mitochondrial light strand promoter DNA into a U-turn shape via its HMG boxes (PubMed : 1737790). Required for maintenance of normal levels of mitochondrial DNA (PubMed : 19304746, PubMed : 22841477). May play a role in organizing and compacting mitochondrial DNA (PubMed : 22037171).
