CC   -!- FUNCTION: Activator for both CDC42 and RAC1 by directly engaging these
CC       Rho GTPases and acting as potent guanine nucleotide exchange factor
CC       (GEF). This activation results in actin cytoskeleton rearrangements and
CC       stimulates membrane ruffling, promoting bacterial entry into non-
CC       phagocytic cells (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}. Note=Secreted via the
CC       type III secretion system 1 (SPI-1 TTSS). {ECO:0000250}.
CC   -!- MISCELLANEOUS: Encoded within a lambda-like prophage region with
CC       similarity to GIFSY phages.
CC   -!- SIMILARITY: Belongs to the GEF (guanine exchange factor) SopE family.
CC       {ECO:0000305}.
