title: Evidence for phosphorylation of actin by the insulin receptor-associated protein kinase from human placenta.
abstract: A purified preparation of rabbit muscle actin (43-kDa protein) is phosphorylated at tyrosine residues when incubated with solubilized insulin receptor from human placenta. Phosphorylation of the 95-kDa receptor subunit and of 43-kDa protein is stimulated by insulin and vanadate, respectively; however, the mode of action of the two agents is distinguishable.
