An antiserum to the insulin receptor mimicked insulin's acute actions on glucose transport, phosphorylation of integral membrane proteins, and internalization of the insulin receptor in isolated rat adipose cells. These insulinomimetic actions of the antiserum occurred without the equivalent increase in phosphorylation of the β subunit of the insulin receptor observed with insulin. Thus, a role of receptor phosphorylation in acute insulin action is now questioned.
