The significance of regulatory light chain phosphorylation in cardiac physiology.

ABSTRACT: It has been over 35 years since the first identification of phosphorylation of myosin light chains in skeletal and cardiac muscle. Yet only in the past few years has the role of these phosphorylations in cardiac dynamics been more fully understood. Advances in this understanding have come about with further evidence on the control mechanisms regulating the level of phosphorylation by kinases and phosphatases. Moreover, studies clarifiying the role of light chain phosphorylation in short and long term control of cardiac contractility and as a factor in cardiac remodeling have improved our knowledge. Especially important in these advances has been the use of gain and loss of function approaches, which have not only testedthe role of kinases and phosphatases, but also the effects of loss of R
