Abstract

Mitochondria have their own genome, which is essential for proper oxidative phosphorylation needed for a large part of ATP production in a cell. Although mitochondrial DNA-less (rho0) cells can survive under special conditions, the integrity of the mitochondrial genome is critical for survival of multicellular organisms. Mitochondrial transcription factor A (TFAM), originally cloned as transcription factor, is essential for the maintenance of mtDNA. Recently, it has become known that TFAM plays critical roles in multiple aspects to maintain the integrity of mitochondrial DNA: transcription, replication, nucleoid formation, damage sensing, and DNA repair. The effects of TFAM in these aspects are intimately related to each other and to function as a whole for the purpose of maintenance of mtDNA.
