the role of the insulin receptor tyrosine kinase ( protein-tyrosine kinase , ec 2.7.1.112 ) in various rapid insulin effects was studied by injecting four different cell types ( by osmotic lysis of pinocytotic vesicles ) with a monoclonal antibody that specifically inhibits the kinase activity of the insulin receptor and the closely related receptor for insulin-like growth factor ( igf ) -i .
