Adenosine Diphosphate 137-140 insulin receptor Homo sapiens 65-81 8200911-9 1994 However, a monoclonal antibody to the insulin receptor (MA-20) at equimolar concentrations with insulin equally inhibits pertussis toxin-catalyzed ADP ribosylation of Gi without activating tyrosine kinase or insulin receptor autophosphorylation. Adenosine Diphosphate 147-150 insulin receptor Homo sapiens 38-54 1385393-1 1992 When the catalytically active, tyrosyl-phosphorylated form of insulin receptor was isolated from human placenta and treated with ADP, only partial dephosphorylation was observed. Adenosine Diphosphate 129-132 insulin receptor Homo sapiens 62-78 1385393-2 1992 This observation suggests the existence of two distinct classes of phosphotyrosyl residues of the phosphorylated insulin receptor: one in which the phosphoryl groups undergo reversible transfer to ADP and one in which they do not. Adenosine Diphosphate 197-200 insulin receptor Homo sapiens 113-129 1385393-8 1992 The dependence of the degree of phosphorylation of insulin receptor on the ATP:ADP ratio may provide a mechanism for modulating the cellular response to insulin. Adenosine Diphosphate 79-82 insulin receptor Homo sapiens 51-67
