A specific precipitating antibody against chicken gizzard myosin light chain kinase (MLCK) has been produced in rabbits. The antibody inhibited enzyme activity in a dose-dependent manner with 11 moles of antibody required to inhibit 80% of the activity of one mole MLCK. Crude homogenates from various chicken tissues were analyzed by SDS-polyacrylamide gel electrophoresis, and the proteins were transferred onto nitrocellulose sheets and reacted with antibody. In each case, the antibody bound to only one protein with a molecular weight of approximately 130,000. These data suggest the MLCK present in all types of muscle as well as non-muscle tissues is of the same molecular weight. Indirect immunofluorescent microscopy of non-muscle tissue culture cells revealed MLCK to be localized in the spindle apparatus and midbody of mitotic cells and on the stress fibers and in the nucleolus of interphase cells. The nucleolar localization was confirmed by electron microscopy and shown to be restricted to the fibrillar region. In myofibrils isolated from skeletal and cardiac muscle, anti-MLCK decorated the actin-containing I bands of the sarcomere. These results are consistent with the suggestion that MLCK and calmodulin are intermediates in the regulation of cell motility by calcium.
