title: Nucleotide sequence analysis of varicella-zoster virus glycoprotein E epitope coding regions.
abstract: Varicella-zoster virus (VZV) glycoprotein E [gE] contains 623 amino acid residues. Fifty percent of the gE gene, codons 39 to 344 that encompasses two epitope coding regions e1 and c1, was sequenced and analyzed for variation among the 30 VZV isolates. A total of eleven isolates showed variance when compared with Dumas VZV strain sequence through base substitutions, with two isolates showing an amino acid change of tryptophan to arginine outside the coding regions of the epitopes e1 and c1 that are recognized by monoclonal antibodies 4F9 and c1, respectively. The results suggest that these epitopes were stable in the various VZV isolates. Thus, VZV glycoproteins with conserved epitopes are suitable candidates for both primary and booster vaccines.
