1. Sorting of tropomyosin isoforms in discrete intracellular locations is developmentally regulated. 2. Normal expression of nebulette is essential for the assembly and tropomyosin . 3. The thin filament is made of actin, tropomyosin , and troponin. 4. Calcium ions then bind to troponin, which is associated with tropomyosin . 5. There is no evidence for active transport of tropomyosin isoforms to specific locations. 6. The binding of caldesmon is strongly influenced by tropomyosin . 7. The capping activity of this protein is dependent on its association with tropomyosin . 8. Tropomyosins are often categorised into two groups, muscle tropomyosin isoforms and nonmuscle tropomyosin isoforms. 9. Tropomyosins are often categorised into two groups, muscle tropomyosin isoforms and nonmuscle tropomyosin isoforms. 10. Within mammals, four genes are responsible for generating more than 40 different tropomyosin isoforms.
