Mitochondrial transcription factor A (TFAM) plays an important role in mitochondrial DNA (mtDNA) transcription and replication. In some experimental settings, TFAM expression parallels parameters of mitochondrial biogenesis, which led to a widespread acceptance of TFAM as marker of mitochondrial biogenesis. We modulated TFAM expression in several experimental systems and observed that it fails to consistently parallel mtDNA copy number and expression of mtDNA-encoded polypeptides. We suggest that the use of TFAM as a marker of mitochondrial biogenesis should be avoided outside of systems in which its performance has been carefully validated.

In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.
A multi-pass transmembrane protein that contains a C-terminal RING finger domain. It localizes to the PEROXISOME membrane and is essential for peroxisome biogenesis. Mutations in the PEX2 gene are associated with ZELLWEGER SYNDROME and INFANTILE REFSUM DISEASE.

Mitochondrial anion carrier proteins that function as dimers and form proton channels in the INNER MITOCHONDRIAL MEMBRANE which creates proton leaks and uncouples OXIDATIVE PHOSPHORYLATION from ATP synthesis, resulting in the generation of heat instead of ATP.
Diseases caused by abnormal function of the MITOCHONDRIA. They may be caused by mutations, acquired or inherited, in mitochondrial DNA or in nuclear genes that code for mitochondrial components. They may also be the result of acquired mitochondria dysfunction due to adverse effects of drugs, infections, or other environmental causes.
