Abstract

There is a myriad of activities that involve mitochondria that are crucial for maintaining cellular equilibrium and genetic stability. In the pathophysiology of neurodegenerative illnesses, mitochondrial transcription influences mitochondrial equilibrium, which in turn affects their biogenesis and integrity. Among the crucial proteins for keeping the genome in optimal repair is mitochondrial transcription factor A, more commonly termed TFAM. TFAM's non-specific DNA binding activity demonstrates its involvement in the control of mitochondrial DNA (mtDNA) transcription. The role of TFAM in controlling packing, stability, and replication when assessing the quantity of the mitochondrial genome is well recognised. Despite mounting evidence linking lower mtDNA copy numbers to various age-related diseases, the correlation between TFAM abundance and neurodegenerative disease remains insufficient. This review delves into the link between neurodegeneration and mitochondrial dysfunction caused by oxidative stress. Additionally, the article will go into detail about how TFAM controls mitochondrial transcription, which is responsible for encoding key components of the oxidative phosphorylation (OXPHOS) system.
