TFAM is described as a one of the core mitochondrial transcription factors. It plays an important role in the recruitment of mitochondrial RNA polymerase and the T2BM transcription factor to initial and activate the transcription process. One of the main roles is to coat and pack mtDNA into nucleoids by forming a U-turn on the mtDNA and creating cross strand interactions. It is also plays a role in the assembly of mitochondrial ribosomes. It can bind to RNA on the translating ribosome and either prevent it from exiting, stabilize it, or enhance its translation process.
TFAM is involved in a crease in mitochondrial membrane potential called mitochondrial cristae biogenesis. It binds to the proton channel of the inner membrane, this increases the amount of free protons within mitochondria and an increase in membrane potential. This causes release of ATP by opening a channel between two subunits of ClpB protein that are normally attached to each other, which allows for the release of ATP. Mitochondrial cristae are small folds in the mitochondrial membrane that have three membranes inside them and allow for diffusion of ions and molecules. Mitochondria need to be able to create these folds so they can expand their surface area when organelles divide. This process is called mitochondrial cristae biogenesis or MCP formation.
TFAM is a member of the high mobility group (HMG-box) family of proteins. It can function in unwinding, bending and binding mtDNA without any sequence specificity. One of the main functions is in maintaining and organising mtDNA into nucleoids. Furthermore, it is also essential for mitochondrial transcription initiation process.
Human TFAM ELISA kit can be used for measuring amounts of transcription factor A, mitochondrial (TFAM) present in human samples of serum, tissue homogenates, other biological fluids and plasma.
