Gene Information from Publications

Publication Link Summary of findings
18032382 A troponin T mutation that causes infantile restrictive cardiomyopathy increases Ca2+ sensitivity of force development and impairs the inhibitory properties of troponin
16157639 The crystal structure of troponin suggests that the Ca2+-binding to the regulatory TnC site displaces the N-terminal portion of TnI from actin/tropomyosin, thereby altering mobility/flexibility of the troponin/tropomyosin strand on the actin filament.
16199542 Observational study of gene-disease association. (HuGE Navigator)
16754800 Observational study of gene-disease association. (HuGE Navigator)
17101185 Observational study of gene-disease association. (HuGE Navigator)
18175163 Observational study of genotype prevalence. (HuGE Navigator)
18092822 These results suggest that the perturbations of the N-domain caused by the Trp mutation disturb the interaction between TnC and TnI, which in turn diminishes the activity in fibers.
18042489 Modulation of cardiac troponin C function by the cardiac-specific N-terminus of troponin I: influence of PKA phosphorylation and involvement in cardiomyopathies.
17101185 spectrum of mutations in cardiac hypertrophy patients
17587709 Persistently increased serum concentrations of cardiac troponin (cTn) in patients with acutely decompensated heart failure are predictive of adverse outcomes.
