Glycoprotein H (gII/gp108) and glycoprotein L form a functional complex which plays a role in penetration, but not in attachment, of bovine herpesvirus 1.
The glycoproteins of bovine herpesvirus 1 (BHV-1) play important roles in the interactions between virions and target cells. A 108 kDa glycoprotein, designated gII or gp 108, has been identified by two different panels of monoclonal antibodies. The gII- and gp 108-specific monoclonal antibodies were shown to react with the same protein, which was identified by N-terminal sequencing as the homologue of herpes simplex virus type 1 (HSV-1) gH. When BHV-1 gH was purified by immunoadsorbent chromatography, gL was co-purified. The gH-gL complex induced the production of antibodies that neutralized virus infectivity and inhibited virus penetration. Affinity-purified gH-gL did prevent penetration, but not attachment of BHV-1, which suggests that the gH-gL complex is essential for penetration of BHV-1 into susceptible cells.
