Abstract
Caldesmon induces inhibition of MG2+‐ATPase activity of actomyosin and relaxation of skinned fibers of chicken gizzard smooth muscle without influencing the level of myosin light chain‐1 phosphorylation. Both these effects are reversed by calmodulin at a high molar excess over caldesmon in the presence of Ca2+.Keywords
