In vitro tyrosine phosphorylation studies on RAS proteins and calmodulin suggest that polylysine like basic peptides or domains may be involved in interactions between insulin receptor kinase and its substrate . ^^^ Since the tyrosine phosphorylation of calmodulin by the insulin receptor kinase in vitro requires cofactors such as protamine and poly ( L lysine ) , we examined the possibility that poly ( L lysine ) may also potentiate the interaction between RAS proteins and the insulin receptor . ^^^ Further examination of the role of poly ( L lysine ) in potentiating tyrosine phosphorylation of the HRAS protein and calmodulin by purified insulin receptor kinase indicates that poly ( L lysine ) affects the conformation of these protein substrates as well as that of the receptor kinase domain . ^^^

The insulin receptor contains a calmodulin binding domain . ^^^ Because binding of insulin to its receptor represents the initial site of insulin action in the plasma membrane , studies were undertaken to determine whether the insulin receptor is a calmodulin binding protein . ^^^ Preparations enriched in the insulin receptor and calmodulin binding proteins were isolated from detergent solubilized rat adipocyte membranes by chromatography with wheat germ agglutinin agarose and calmodulin conjugated Sepharose , respectively . ^^^ Binding and photocovalent cross linking of iodine 125 labeled calmodulin to these affinity purified preparations and to isolated plasma membranes , followed by immunoadsorption with insulin receptor antibodies bound to protein A Sepharose , resulted in significant purification of a binding complex of 110K to 140K . ^^^ These results indicate that the adipocyte insulin receptor or a polypeptide closely associated with the receptor is a calmodulin binding protein . . ^^^

The role of polybasic compounds in determining the tyrosyl phosphorylation of calmodulin by the human insulin receptor . ^^^ A highly purified human insulin receptor preparation was shown to effect receptor autophosphorylation and the phosphorylation of poly ( GluTyr ) but not that of calmodulin . ^^^ Polybasic substances such as poly L arginine , histone H 1 and protamine sulphate all promoted calmodulin phosphorylation by the insulin receptor in a similar biphasic dose dependent fashion . ^^^ It is suggested that calmodulin can be phosphorylated by the insulin receptor only when it is cross linked in a multivalent fashion to a suitable polybasic substance so that it forms large multimeric aggregates . ^^^
