Abstract

The presence of protein phosphokinase activity in a purified nuclear-membrane preparation from adult rat liver was demonstrated by measuring the incorporation of ³²P from γ-³²P-ATP into endogenous nuclear-membrane proteins as well as into the exogenous protein substrates, dephosphophosvitin (DPV) and lysine-rich histone (LRH). The activity of this enzyme toward DPV was 60 times greater than that toward LRH. cAMP and cGMP did not appear to affect the phosphorylation of endogenous-membrane proteins.
