evidence suggesting that this kinase activity is responsible for c-protein phosphorylation includes 1 ) the phosphorylation of c-proteins in the fractions where they overlap with the kinase , 2 ) the phosphorylation of added c-protein by fractions of the casein kinase which lack detectable c-protein , and 3 ) the similarities in catalytic properties of the casein kinase- and c-protein-phosphorylating activities .
