Investigations into the pathobiology of thin-filament myopathies.

Abstract excerpt

Mutations in actin and tropomyosin, identified in patients with myopathic disease have been used in tissue culture models and functional studies with a view to understand how these mutations impact on skeletal muscle structure and function and result in muscle weakness. The likely mode of pathogenesis in these disorders is via a dominant negative effect i.e., the production of 'poison' proteins that interfere...
