Mitochondrial transcription factor A (TFAM) is a mitochondrial DNA (mtDNA) binding protein that maintains the mitochondrial genome by regulating replication, transcription, and packaging of mtDNA.{59160} It contains two high mobility group (HMG) box domains that bind mtDNA and induce a conformational change that permits binding of mitochondrial RNA polymerase (mtRNAP) to the promoter start site. TFAM binds to mtRNAP, recruiting mitochondrial transcription factor 2 (TFB2M) and initiating transcription. TFAM also maintains mitochondrial genome stability by non-specifically binding to mtDNA, packaging it into nucleoid-like structures. Homozygous knockout of Tfam in mice is embryonic lethal whereas heterozygous Tfam knockdown mice are viable but have reduced mtDNA copy numbers and decreased activity of the mitochondrial respiratory chain complexes I, III, IV, and V in the heart.{59161} Genetic overexpression of Tfam reduces age-induced accumulation of lipid peroxidation products in the brain and memory impairments in mice.{59162} Increased tumor TFAM protein levels are associated with increased tumor size in patients with breast cancer.{59163} SNPs in TFAM have been identified in patients with a variety of neurodegenerative disorders, including Parkinson’s disease, Alzheimer’s disease, and Huntington’s disease.{59160} Cayman’s TFAM Polyclonal Antibody can be used for Western blot (WB) applications. The antibody recognizes TFAM at approximately 24 kDa from human samples.

Cayman Chemical’s mission is to help make research possible by supplying scientists worldwide with the basic research tools necessary for advancing human and animal health. Our utmost commitment to healthcare researchers is to offer the highest quality products with an affordable pricing policy.
Our scientists are experts in the synthesis, purification, and characterization of biochemicals ranging from small drug-like heterocycles to complex biolipids, fatty acids, and many others. We are also highly skilled in all aspects of assay and antibody development, protein expression, crystallization, and structure determination.
Over the past thirty years, Cayman developed a deep knowledge base in lipid biochemistry, including research involving the arachidonic acid cascade, inositol phosphates, and cannabinoids. This knowledge enabled the production of reagents of exceptional quality for cancer, oxidative injury, epigenetics, neuroscience, inflammation, metabolism, and many additional lines of research.
Our organic and analytical chemists specialize in the rapid development of manufacturing processes and analytical methods to carry out clinical and commercial GMP-API production. Pre-clinical drug discovery efforts are currently underway in the areas of bone restoration and repair, muscular dystrophy, oncology, and inflammation. A separate group of Ph.D.-level scientists are dedicated to offering Hit-to-Lead Discovery and Profiling Services for epigenetic targets. Our knowledgeable chemists can be contracted to perform complete sample analysis for analytes measured by the majority of our assays. We also offer a wide range of analytical services using LC-MS/MS, HPLC, GC, and many other techniques.
