Protein kinase activity of the multiprotein complex. (A) Phosphorylated polypeptides were revealed upon incubation of the Mono S fraction in the presence of [γ-32P] ATP alone (lane 1), or in combination with histone H1 (lane 2), histone plus p21 (lane 3) or histone plus Olomucine (lane 4). (B) The Mono S fraction was immunoprecipitated with anti-cyclin A antibodies and the immunoprecipitated material was probed with antibodies against cyclin A (lane 1) or anti-phosphoSer/Thr (lane 2).
