based on the assumption that pp60c-src might play a role in the control of cell proliferation , we have studied its behaviour as a substrate for phosphorylation known to occur when quiescent , serum-deprived cells are stimulated to enter cell cycle following addition of either serum , platelet-derived growth factor or the phorbol ester derivative , 12-o-tetradecanoyl-phorbol-13-acetate .
