Distance distributions and anisotropy decays of troponin C and its complex with troponin I [PDF]
We used frequency domain measurements of fluorescence resonance energy transfer to recover the distribution of distances between Met 25 and Cys 98 in rabbit skeletal troponin C. These residues were labeled with dansylaziridine as energy donor and 5-(iodoacetamido)eosin as acceptor and are located on the N- and C-terminal lobes of the two-domain protein,

Computational Studies of Cardiac and Skeletal Troponin
Troponin is a key regulatory protein in muscle contraction, consisting of three subunits troponin C (TnC), troponin I (TnI), and troponin T (TnT). Calcium association to TnC initiates contraction by causing a series of dynamic and conformational changes ...

Troponin T3 regulates nuclear localization of the calcium channel Cavβ1a subunit in skeletal muscle [PDF]
The voltage-gated calcium channel (Cav) β1a subunit (Cavβ1a) plays an important role in excitation-contraction coupling (ECC), a process in the myoplasm that leads to muscle-force generation. Recently, we discovered that the Cavβ1a subunit travels to the

A Case Series of Disproportionate Elevations of Cardiac Troponin and Macrotroponin in Fabry Disease [PDF]
Fabry disease is a rare X-linked lysosomal storage disorder that causes progressive cellular accumulation of glycosphingolipids, leading to various end-organ manifestations such as chronic kidney disease and cardiomyopathy.

Effects of troponin T cardiomyopathy mutations on the calcium sensitivity of the regulated thin filament and the actomyosin cross-bridge kinetics of human β-cardiac myosin. [PDF]
Hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM) lead to significant cardiovascular morbidity and mortality worldwide. Mutations in the genes encoding the sarcomere, the force-generating unit in the cardiomyocyte, cause familial forms ...

The calcium‐induced switch in the troponin complex probed by fluorescent mutants of troponin I [PDF]
The Ca2+‐induced transition in the troponin complex (Tn) regulates vertebrate striated muscle contraction. Tn was reconstituted with recombinant forms of troponin I (TnI) containing a single intrinsic 5‐hydroxytryptophan (5HW). Fluorescence analysis of these mutants of TnI demonstrate that the regions in TnI that respond to Ca2+ binding to the ...

Utility of B-type natriuretic peptide in predicting medium-term mortality in patients undergoing major non-cardiac surgery [PDF]
We assessed the ability of pre-operative B-type natriuretic peptide (BNP) levels to predict medium-term mortality in patients undergoing major noncardiac surgery.

Bovine cardiac troponin subunits: binary complexes and reconstitution of whole troponin
The reconstitution of bovine cardiac troponin from its subunits has been investigated using hydrodynamic techniques. Gel filtration (Sephacryl S‐300) and sedimentation velocity experiments indicate that troponin‐C and troponin‐I from a stable binary complex (1:1 mole ratio) with an apparent Stokes' radius of 36 Å (frictional ratio = 1.6).
