during this procedure , a calmodulin-binding protein of mr 141000 , which previously co-purified with the myosin light-chain kinase , is removed and shown to be a distinct protein on the basis of lack of kinase activity , different chymotryptic peptide maps , lack of cross-reactivity with a monoclonal antibody to turkey gizzard myosin light-chain kinase , and lack of phosphorylation by the purified catalytic subunit of cyclic amp-dependent protein kinase .
