Functional effects of substitutions I92T and V95A in actin-binding period 3 of tropomyosin

Tropomyosin polymerizes along actin filaments and together with troponin regulates muscle contraction in a Ca-dependent manner. Actin-binding periods are homologous residues, which repeat along tropomyosin sequence, form tropomyosin-actin interface and determine regulatory functions. To learn how pe...
