Phosphorylation of simian virus 40 large T antigen (large T) was investigated in vitro. "Autophosphorylation" of large T resulted in the modification of Ser106, Ser112, Ser123, Thr124, either Ser676, Ser677, or Ser679, and Thr701. All of these residues were also found to be phosphorylated in vivo. Reaction of large T with purified casein kinase I resulted in phosphorylation of Ser123, possibly Thr124, and either Ser676, Ser677, or Ser679, while purified casein kinase II phosphorylated Ser106 and possibly Ser112. Submolar amounts of phosphate were transferred to large T indicating that only a fraction of large T served as substrate for the casein kinases. Removal of serine-bound phosphate did not affect the subsequent autophosphorylation or phosphorylation by casein kinase I and II. No phosphorylation at in vivo sites was observed with the cAMP-, cGMP-, or Ca2+/phospholipid-dependent protein kinases, or with the protease-activated kinase I and II.
