title: [CAMP mediated cell growth regulation. I. Characterization of protein kinases in CHO cells].
abstract: Protein kinases in wild-type CHO cells have been characterized. Cells cultured on MEM were collected, homogenized and the extract assayed for protein kinase activity. DEAE cellulose chromatography of 30.000xg extract yields 2 peaks of protein kinases activity, PKI and PKII. The two peaks when analyzed for the binding of 8-N3-(32P)cAMP show two subunits RI and RII and a RI not associated with the enzymatic activity, named RF. This characterization allows us to discuss the meaning of protein kinases in the modulation of the growth regulating effects of cAMP.
