Cardiac troponin C (cTnC) is a key effector in cardiac muscle excitation-contraction coupling as the Ca2+ sensing subunit responsible for controlling contraction. In this study, we generated several FRET sensors for divalent cations based on cTnC fla

Striated muscle contraction is regulated by dynamic and cooperative interactions among Ca2+, troponin and tropomyosin on the thin filament. While Ca2+ regulation has been extensively studied, little is known about the dynamics of individual regulator

The absence of a crystal structure of the calcium free state of the cardiac isoform of the troponin complex has hindered our understanding of how the simple binding of Ca2+ triggers conformational changes in troponin which are then propagated to enab

Duchenne muscular dystrophy (DMD) associated cardiomyopathy remains incurable. Connexin 43 (Cx43) is upregulated and remodeled in the hearts of mdx mice, a mouse model of DMD. Hearts from Wild Type, mdx, and mdx:Cx43(+/-) mice were studied before (4-

Aims Duchenne muscular dystrophy (DMD) is an inherited devastating muscle disease with severe and often lethal cardiac complications. Emerging evidence suggests that the evolution of the pathology in DMD is accompanied by the accumulation of mitochon

Aims Nicotinamide adenine dinucleotide oxidases (NOXs) are important contributors to cellular oxidative stress in the cardiovascular system. The NOX2 isoform is upregulated in numerous disorders, including dystrophic cardiomyopathy, where it drives t
Actomyosin kinetics in both skinned skeletal muscle fibers at maximum Ca2+-activation and unregulated in vitro motility assays are modulated by solvent microviscosity in a manner consistent with a diffusion limited process. Viscosity might also influ

Troponin C (TnC), the Ca2+ binding subunit in striated muscle, is central to regulation of contraction. Crystal structures of skeletal TnC show a rigid, elongated central helix, whereas solution NMR shows it is flexible and unstructured in the absenc

We have previously shown with skinned skeletal muscle fibers at maximum Ca2+ activation and unregulated in vitro motility assays that solvent viscosity modulates actomyosin function in a manner consistent with diffusional limitation of a kinetic proc
