Physiological consequences of tropomyosin mutations associated with cardiac and skeletal myopathies.

Abstract excerpt

Mutations have been identified in alpha-tropomyosin (Tm), a key regulatory protein in striated muscle cells, that are associated with a human cardiac myopathy, hypertrophic cardiomyopathy (FHC) and a human skeletal myopathy, nemaline myopathy (NM). In this review, we highlight experiments aimed at identifying the underlying mechanisms by which mutations in alpha-Tm cause inherited diseases of cardiac and skeletal...
