Molecular mechanisms of the regulation of ATPase cycle in striated muscle [PDF]
New data on the molecular mechanism of the regulation of ATPase cycle by troponin-tropomyosin system have been obtained in reconstructed muscle fibers by using the polarized fluorescence technique, which allowed us following the azimuthal movements of ...

Schematic overview showing that forkhead box O6, opposite strand (Foxo6os) acts as a “scaffold”, directly binding myosin‐binding protein‐C (MYBPC3) and recruiting protein kinase C (PKC‐α) to mediate site‐specific phosphorylation of MYBPC3. This post‐translational modification supports cardiac contraction by regulating L‐type Ca2+ channels, especially ...

At low free Ca2+, the actin binding proteins tropomyosin, troponin I, troponin T and troponin C inhibit contraction in striated muscles. Ca2+ activation alters the position of tropomyosin on actin to uncover binding sites for high affinity forms of ...

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

Deciphering the skeletal interoceptive circuitry to control bone homeostasis
This review introduces the skeletal interoceptive circuitry, covering the ascending signals from bone tissues to the brain (sensors), the central neural circuits that integrate this information and dispatch commands (CPU), and the descending pathways that regulate bone homeostasis (effectors).

The Conformational Stabilities of Tropomyosins [PDF]
The stability to denaturation by heat and guanidine hydrochloride of seven vertebrate (including skeletal, cardiac and smooth muscle) tropomyosins and three invertebrate tropomyosins was examined. The transition profiles were discontinuous and in many cases distinct plateaux were observed which indicated the presence of unique partially unfolded states

Equilibrium self‐association of tropomyosin [PDF]
It has recently been reported that tropomyosin exists exclusively as a dimer in physiological salt conditions. It is shown in the present work using analytical ultracentrifugation that, on the contrary, tropomyosin is in equilibrium between monomer, dimer and tetramer with a weak tendency to dimerize and tetramerize. Such a finding has consequences for

Abstract Tissue tension encompasses the mechanical forces exerted on solid tissues within animal bodies, originating from various sources such as cellular contractility, interactions with neighboring cells and the extracellular matrix. Emerging evidence indicates that an imbalance in such forces can influence structural organization, homeostasis, and ...
