electrophoresis of heat-stable proteins prepared from hormone-treated 32p-labeled fat cells showed that insulin caused a dephosphorylation of the 32,000 da phosphoprotein by 30 % ( p less than 0.01 ) , whereas isoproterenol stimulated 32p incorporation in this protein by 35 % compared to control ( p less than 0.05 ) .
