Protein Structure
UniProt Annotation
Function Troponin is the central regulatory protein of striated muscle contraction. Tn consists of three components: Tn-I which is the inhibitor of actomyosin ATPase, Tn-T which contains the binding site for tropomyosin and Tn-C. The binding of calcium to Tn-C abolishes the inhibitory action of Tn on actin filaments.
Subcellular Localization
Disease Associations Cardiomyopathy, dilated 1Z (CMD1Z) [MIM:611879]: A disorder characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and arrhythmia. Patients are at risk of premature death. {ECO:0000269PubMed:15542288}. Note=The disease is caused by mutations affecting the gene represented in this entry.Cardiomyopathy, familial hypertrophic 13 (CMH13) [MIM:613243]: A hereditary heart disorder characterized by ventricular hypertrophy, which is usually asymmetric and often involves the interventricular septum. The symptoms include dyspnea, syncope, collapse, palpitations, and chest pain. They can be readily provoked by exercise. The disorder has inter- and intrafamilial variability ranging from benign to malignant forms with high risk of cardiac failure and sudden cardiac death. {ECO:0000269PubMed:11385718, ECO:0000269PubMed:18572189}. Note=The disease is caused by mutations affecting the gene represented in this entry.
