Abstract excerpt
Expression of tropomyosin protein, an essential component of the thin filament, has been found to be drastically reduced in cardiac mutant hearts of the Mexican axolotl (Ambystoma mexicanum) with no formation of sarcomeric myofibrils. Therefore, this naturally occurring cardiac mutation is an app...
