  • Description
    Rat monoclonal [MAC 141] to Tropomyosin
  • Specificity
    Antibody reacts with tropomyosin in Lethocerus and Drosophila flight and non-flight muscle and with tropomyosin in flight muscles of all other insect species tested. Antibody reacts with Troponin H (TnH) in Lethocerus flight muscle, the 33 and 34 isoforms of TnH in Drosophila and proteins of TnH molecular weight in flight muscles of other Diptera and Lepidoptera. Antibody also reacts with tropomyosin in muscles of Crustacea and Caenorhabditis (nematode).

  • Relevance
    Tropomyosin is a dimeric coiled coil protein that binds along the length of actin filaments. It is associated with the thin filaments of muscle cells and the microfilaments of nonmuscle cells. Chicken embryo fibroblasts (CEF) contain five isoforms of tropomyosin (a, b, 1, 2, and 3), identified as such by their different apparent molecular masses after separation by SDS-PAGE, but similar biochemical properties, such as resistance to heat and organic solvents, the ability to bind to F actin filaments, and the lack of proline and tryptophan.
