RESUMO
A type-specific monoclonal antibody, LP10, precipitated a glycoprotein with a molecular weight of approximately 59,000 from purified herpes simplex virus type 1. Although this glycoprotein was similar in size to glycoprotein D (gD), it was shown to be less abundant in both virions and infected cells, to migrate more rapidly in its precursor form, to incorporate glucosamine but not mannose, and to have a more stable precursor in tunicamycin-treated cells than the gD precursor (pgD). Immunoassays of cells infected with insertion recombinants and intertypic recombinants localized the gene coding for the target antigen of LP10 to the unique short (Us) region at map units 0.892 to 0.924 excluding gD. The target antigen of LP10 was then definitively mapped to the Us4 open reading frame by immunoprecipitation of a polypeptide synthesized by in vitro translation of a Us4-specific transcript prepared by using an SP6 cloning This newly identified glycoprotein product of the Us4 gene of herpes simplex virus type 1 is distinct from the previously identified gB1, gC1, gE1, and gH1.
