Mitochondrial transcription factor A (TFAM) is a high-mobility group (HMG) protein and is made up of two HMG-box domains. The TFAM gene is located on the human chromosome at 10q21.1.
Immunogen
TFAM (NP_003192.1, 1 a.a. ~ 246 a.a) full-length human protein.
Anti-TFAM antibody produced in rabbit has been used in western blotting (1:1000)[1][2] and immunofluorescence[2].
Biochem/physiol Actions
Mitochondrial transcription factor A (TFAM) is involved in mitochondrial DNA (mtDNA) synthesis, expression, and packaging. It is also involved in regulating the aggregation of mtDNA. TFAM stabilizes the mtDNA by binding to it in a sequence-depending manner and forms a nucleoid.
Physical form
Solution in phosphate buffered saline, pH 7.4

Impaired mitochondrial function and an increased number of mutations in mitochondrial DNA (mtDNA) has been found in brains of patients with late-onset Alzheimer's disease (LOAD). The TFAM-gene encodes the mitochondrial transcription factor A, a protein that controls the transcription, replication

Background: Ageing is associated with alterations to skeletal muscle oxidative metabolism that may be influenced by physical activity status, although the mechanisms underlying these changes have not been unraveled. Similarly, the effect of resistance exercise training (RET) on skeletal muscle
Bed rest (BR) results in significant impairments in skeletal muscle metabolism. Mitochondrial metabolism is reportedly highly sensitive to disuse, with dysregulated fission-fusion events and impaired oxidative function previously reported. The effects of clinically relevant short-term BR (≤5 days) on mitochondrial protein
For advanced oral squamous cell carcinoma (OSCC), increasing sensitivity to chemotherapy is a major challenge in improving treatment outcomes, and targeting cytoprotective processes that lead to the chemotherapy resistance of cancer cells may be therapeutically promising. Tumor-suppressive microRNAs (miRNAs) can
Human mitochondrial transcription factor A (TFAM) is a high-mobility group (HMG) protein at the nexus of mitochondrial DNA (mtDNA) replication, transcription, and inheritance. Little is known about the mechanisms underlying its posttranslational regulation. Here, we demonstrate that TFAM is phosphorylated
