CC   -!- FUNCTION: In epithelial cells, the heterodimer gE/gI is required for
CC       the cell-to-cell spread of the virus, by sorting nascent virions to
CC       cell junctions. Once the virus reaches the cell junctions, virus
CC       particles can spread to adjacent cells extremely rapidly through
CC       interactions with cellular receptors that accumulate at these
CC       junctions. Implicated in basolateral spread in polarized cells. In
CC       neuronal cells, gE/gI is essential for the anterograde spread of the
CC       infection throughout the host nervous system. Together with US9, the
CC       heterodimer gE/gI is involved in the sorting and transport of viral
CC       structural components toward axon tips.
CC   -!- SUBUNIT: Interacts with gE. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion membrane {ECO:0000250}; Single-pass
CC       membrane protein {ECO:0000250}. Host cell membrane {ECO:0000305};
CC       Single-pass type I membrane protein {ECO:0000305}. Host cell junction
CC       {ECO:0000250}. Host Golgi apparatus membrane {ECO:0000250}; Single-pass
CC       type I membrane protein {ECO:0000250}. Note=During virion
CC       morphogenesis, this protein probably accumulates in the endosomes and
CC       trans-Golgi where secondary envelopment occurs. It is probably
CC       transported to the cell surface from where it is endocytosed and
CC       directed to the trans-Golgi network (TGN). The heterodimer gE/gI then
CC       redistribute to cell junctions to promote cell-cell spread later in the
CC       infection (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the alphaherpesvirinae glycoprotein I family.
CC       {ECO:0000305}.
