Smooth muscle contraction follows an increase in cytosolic Ca 2+ concentration, activation
of myosin light chain kinase, and phosphorylation of the 20-kDa light chain of myosin at Ser …

The signal transduction pathway whereby the TxA 2 (thromboxane A 2 ) mimetic U-46619
activates vascular smooth muscle contraction was investigated in de-endothelialized rat …

Hyperphosphorylation of the cardiac Ca 2+ release channel (ryanodine receptor, RyR2) by
protein kinase A (PKA) at serine-2808 has been proposed to be a key mechanism …

Dissociation of FKBP12.6 from the cardiac Ca 2+ -release channel (RyR2) as a consequence
of protein kinase A (PKA) hyperphosphorylation of RyR2 at a single amino acid residue, …

Integrin-linked kinase (ILK) has been implicated in Ca 2+ - independent contraction of
smooth muscle via its ability to phosphorylate myosin. We investigated the possibility that this …

Smooth muscle contraction is activated by phosphorylation at Ser-19 of LC 20 (the 20 kDa
light chains of myosin II) by Ca 2+ /calmodulin-dependent MLCK (myosin light-chain kinase). …

Multiple calmodulin (CaM) isoforms are expressed in plants, but their biochemical characteristics
are not well resolved. Here we show the differential regulation exhibited by two soya …

Ca 2+ sensitization of smooth muscle contraction depends upon the activities of protein kinases,
including Rho-associated kinase, that phosphorylate the myosin phosphatase targeting …

DAPK1 and ZIPK (also called DAPK3) are closely related serine/threonine protein kinases
that regulate programmed cell death and phosphorylation of non-muscle and smooth muscle …

Smooth muscle contraction is activated by phosphorylation of the 20-kDa light chains of
myosin catalyzed by Ca 2+ /calmodulin (CaM)-dependent myosin light chain kinase (MLCK). …
