title: Co-purification of protein kinase activity with the 58 000 Dalton polypeptide coded for by the early 1B region of human adenovirus type 5.
abstract: Extracts from human adenovirus type 5 (Ad5)-transformed cells were fractionated by ammonium sulphate precipitation, DEAE-Sephacel chromatography and glycerol gradient centrifugation. In all cases, protein kinase activity co-purified with the 58 000 mol. wt. polypeptide (58K) coded for by the early 1B region of Ad5. Kinase activity was also precipitated by an antiserum raised against a synthetic peptide corresponding to the predicted carboxy terminus of 58K. These data suggest that protein kinase activity is associated with 58K, either intrinsically or in an enzyme bound to 58K.
