Abstract:
:Two cyclic AMP-independent protein kinases (CK 1 and CK 2) in the cytosol fraction of AH-66 hepatoma cells have been purified to homogeneity. CK 1 and CK 2 had molecular weights of 36,000 and 340,000, respectively, as determined by gel filtration. CK 1 consists of a single polypeptide and CK 2 is composed of two subunits of 42,000 and 26,000 molecular weights. CK 1 and the 26,000 molecular weight subunit of CK 2 were autophosphorylated. Both enzymes catalyzed the phosphorylation of cytosolic proteins including those with molecular weights of 125,000, 95,000, 56,000, and 40,000.
