The objective of this study was to relate the toxicity of several cantharidin-derivative pesticides with their abilities to inhibit protein phosphatases-1 (PP1) and -2A (PP2A). Cantharidin (CA), endothall, and endothall thioanhydride (ETA) inhibited

The actin-activated ATPase activities of subfragment 1 (S1) produced from gizzard myosin by papain or Staphylococcus aureus protease are different. The activity of the latter is lower, in spite of the presence of intact 20,000-dalton light chains. To

Limited proteolysis of gizzard myosin by alpha-chymotrypsin converted the heavy chain doublet pattern, seen by gel electrophoresis, to a single band. Light chain degradation was not observed and only minor cleavage occurred at other heavy chain sites

The interactions of the catalytic subunit of type 1 protein phosphatase (PP1c) and the N-terminal half (residues 1-511) of myosin phosphatase target subunit 1 (MYPT1) were studied. Biotinylated MYPT1 derivatives were immobilized on streptavidin-biose

It has been established for many years that MLCK is regulated by the intracellular Ca2+ concentration via the formation of the Ca2+ -calmodulin-MLCK complex. A more recent discovery has been that the myosin phosphatase may also be regulated. This is

Myosin phosphorylation is an important mechanism in regulating contractile activity of smooth muscle. The level of myosin phosphorylation depends on the balance of two enzymes, myosin light chain kinase and myosin phosphatase. Recently it has been di

This review has presented some of the recent data on myosin phosphatase from smooth muscle. Although it is not conclusive, it is likely that most of the myosin phosphatase activity is represented by a holoenzyme composed of three subunits. These are:

A unique property of smooth muscle is its ability to maintain force with a very low expenditure of energy. This characteristic is highly expressed in molluscan smooth muscles, such as the anterior byssus retractor muscle (ABRM) of Mytilus edulis, dur

Myosin II light chains (MLC20) are phosphorylated by a Ca2+/calmodulin-activated kinase and dephosphorylated by a phosphatase that has been purified as a trimer containing the delta isoform of type 1 catalytic subunit (PP1C delta), a myosin-binding 1

A myosin phosphatase was purified from chicken gizzard smooth muscle. The holoenzyme is a trimer and consists of 130,000-, 38,000-, and 20,000-Da subunits (in agreement with the results of Alessi et al.: Alessi, D., MacDougall, L. K., Sola, M. M., Ik
