The biosynthesis and function of the gE-gI complex of feline herpesvirus (F
HV) was studied by heterologous expression of the cloned genes in the vacci
nia virus-based vTF7-3 expression system and by analysis of FHV recombinant
s. This work has led to the identification of domains in gI involved in com
plex formation with gE, and to a model for the disulfide-bonded structure o
f gI. The effects of mutations in gI on gE-gI-dependent cell-to-cell transm
ission are discussed. (C) 1999 Elsevier Science B.V. All rights reserved.
