|Calculated MW||28187 Da|
|Application & Usage||The peptide is used for blocking the antibody activity of TFAM. It usually blocks the antibody activity completely in Western blot analysis by incubating the peptide with equal volume of antibody for 30-60 minutes at 37°C. |
|Other Names||Transcription factor A, mitochondrial, mtTFA, Tfam|
|Formulation||50 µg (0.5 mg/ml) in phosphate buffered saline (PBS), pH 7.2, containing 50% glycerol, 1% BSA and 0.02% thimerosal.|
|Reconstitution & Storage||-20 °C|
|Precautions||TFAM Blocking Peptide is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Isoform Mitochondrial binds to the mitochondrial light strand promoter and functions in mitochondrial transcription regulation. Required for accurate and efficient promoter recognition by the mitochondrial RNA polymerase. Promotes transcription initiation from the HSP1 and the light strand promoter by binding immediately upstream of transcriptional start sites. Is able to unwind DNA. Bends the mitochondrial light strand promoter DNA into a U-turn shape via its HMG boxes. Required for maintenance of normal levels of mitochondrial DNA. May play a role in organizing and compacting mitochondrial DNA (By similarity). Isoform Nuclear may also function as a transcriptional activator or may have a structural role in the compaction of nuclear DNA during spermatogenesis (By similarity).|
|Cellular Location||Isoform Mitochondrial: Mitochondrion. Mitochondrion matrix, mitochondrion nucleoid|
|Tissue Location||The mitochondrial isoform is widely expressed while the nuclear isoform is testis-specific|
