CC   -!- FUNCTION: Vaccinia growth factor stimulates cellular proliferation
CC       (hyperplasia) around infected cells. This effect is beneficial for
CC       virus replication in vivo, because poxviruses replicate possibly better
CC       in proliferating cells than in quiescent cells. Acts by binding host
CC       EGFR, inducing its dimerization, autophosphorylation and leading to
CC       activation of several cellular pathways regulating cell proliferation
CC       or cell survival. The activation by host EGFR of mitogen activated
CC       protein kinases (MAPK) and extracellular-signal regulated kinases (ERK)
CC       are essential for the positive effect of vaccinia growth factor on
CC       poxvirus virulence in vivo (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Vaccinia growth factor interacts with host EGFR and promotes
CC       EGFR dimerization. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: [Pro-vaccinia growth factor]: Host membrane
CC       {ECO:0000250|UniProtKB:P01136}; Single-pass type I membrane protein
CC       {ECO:0000250|UniProtKB:P01136}.
CC   -!- SUBCELLULAR LOCATION: [Vaccinia growth factor]: Secreted
CC       {ECO:0000250|UniProtKB:P01136}.
