    A number of proteins were tested as potential substrates for purified rabbit liver calmodulin-dependent glycogen synthase kinase. It was found that liver phenylalanine hydroxylase and several brain proteins including tyrosine hydroxylase, microtubule-associated protein 2, and synapsin I were readily phosphorylated. Brain tubulin was very poorly phosphorylated. These results suggest that calmodulin-dependent glycogen synthase kinase may be a more general protein kinase involved in the regulation of several cellular Ca2+-dependent functions.
