Atomic force microscopy based single-molecule force spectroscopy of smooth muscle myosin light chain kinase strongly indicates the existence of a mechanically triggerable activation pathway analogous to its well-established biochemical regulation pathway via calcium-loaded calmodulin.

Genetic mouse models identify a critical mechanism of myogenic vasoconstriction and reveal the in vivo function of myogenic autoregulation in protecting from organ overperfusion and in maintaining vascular resistance.

Unfair competition, in which a phosphatase and a phosphoprotein inhibitor/substrate mutually sequester each other from competing substrates and enzymes, is a conserved mechanism for the control of PPP family phosphatases.

microRNA-1 plays an essential role in the development and functioning of the heart by ensuring that genes for striated, rather than smooth, muscle are expressed there.
Individual nonmuscle myosin 2 filaments in cells may differ their mechanical and kinetic properties depending on the myosin paralog composition giving the cells a mechanism for fine tuning the output of a given nonmuscle myosin filament.

R788 is part of an allosteric communication pathway that connects the converter at the distal end of the myosin motor domain via the relay helix with switch-2 of the active site.
Quantitative FRET imaging in moving C. elegans shows that stretch-unfolding of twitchin kinase occurs in the active muscle, whereby mechanical activity titrates the signaling pathway of this cytoskeletal kinase.
