Abstract

Troponin (Tn) is the sarcomeric Ca²⁺ regulator for striated (skeletal and cardiac) muscle contraction. On binding Ca²⁺ Tn transmits information via structural changes throughout the actintropomyosin filaments, activating myosin ATPase activity and muscle contraction. Although the Tn-mediated regulation of striated muscle contraction is now well understood, the role of different Tn isoforms in these processes is the subject of intensive investigations. This review addresses the physiological significance of the multiple Tn isoforms in skeletal and cardiac muscles as well as their role in the regulation of contraction.
