these data suggest that relaxin-treatment results in a change in the affinity of mlc kinase for its substrate and modulator and that relaxin inhibits uterine contractile activity by a mechanism which involves a decrease in mlc kinase activity and , in turn , a decrease in phosphorylation of the 20,000-dalton light chains of myosin .
