Abstract: | As part of our vaccine program, we have purified a recombinant form of human cytomegalovirus glycoprotein B that is able to induce high titers of virus-neutralizing antibodies. The isolated protein was found to be phosphorylated at a serine residue in position -7 from the C terminus of the protein. The corresponding synthetic peptide, HLKDSDEEENV, was an efficient in vitro substrate of casein kinase II. |
