The calcium sensitizer drug MCI-154 binds the structural C-terminal domain of cardiac troponin C [PDF]
Biochemistry and Biophysics Reports, 2018 The compound MCI-154 was previously shown to increase the calcium sensitivity of cardiac muscle contraction. Using solution NMR spectroscopy, we demonstrate that MCI-154 interacts with the calcium-sensing subunit of the cardiac troponin complex, cardiac ...

Hypertrophic Cardiomyopathy Mutations of Troponin Reveal Details of Striated Muscle Regulation
Frontiers in Physiology, 2022 Striated muscle contraction is inhibited by the actin associated proteins tropomyosin, troponin T, troponin I and troponin C. Binding of Ca2+ to troponin C relieves this inhibition by changing contacts among the regulatory components and ultimately ...

X-ROS Signaling Depends on Length-Dependent Calcium Buffering by Troponin
Cells, 2021 The stretching of a cardiomyocyte leads to the increased production of reactive oxygen species that increases ryanodine receptor open probability through a process termed X-ROS signaling.

An in silico analysis of troponin I mutations in hypertrophic cardiomyopathy of Indian origin. [PDF]
PLoS ONE, 2013 Hypertrophic Cardiomyopathy (HCM) is an autosomal dominant disorder of the myocardium which is hypertrophied resulting in arrhythmias and heart failure leading to sudden cardiac death (SCD).

Troponin Variants as Markers of Skeletal Muscle Health and Diseases
Frontiers in Physiology, 2021 Ca2+-regulated contractility is a key determinant of the quality of muscles. The sarcomeric myofilament proteins are essential players in the contraction of striated muscles.

The Solution Structure of a Cardiac Troponin C−Troponin I−Troponin T Complex Shows a Somewhat Compact Troponin C Interacting with an Extended Troponin I−Troponin T Component [PDF]
Biochemistry, 2002 We have investigated the structure of the cTnC-cTnI-cTnT(198-298) calcium-saturated, ternary cardiac troponin complex by small-angle scattering with contrast variation. Shape restoration was also applied to the scattering information resulting from the deuterated cTnC subunit, the unlabeled cTnI-cTnT(198-298) subunits, and the entire complex.
