“Autophosphorylation was detected only at temperatures >or=60 degrees C, whereas phosphorylation of exogenous proteins was detectable at 37 degrees C. Similarly, replacement of one of the potential sites of autophosphorylation, Ser(548), with alanine blocked autophosphorylation but not phosphorylation of an exogenous protein, casein.”
