Mitochondrial transcription factor A (TFAM) is a mitochondrial DNA (mtDNA)-binding protein that plays a crucial dual role in the initiation of mitochondrial transcription initiation and mtDNA maintenance. Because TFAM directly interacts with mtDNA, assessing its DNA-binding property can provide useful information. This chapter describes two in vitro assay methods, an electrophoretic mobility shift assay (EMSA) and a DNA-unwinding assay with recombinant TFAM proteins, which both require simple agarose gel electrophoresis. These are used to investigate the effects of mutations, truncation, and posttranslational modifications on this key mtDNA regulatory protein.
