RT "Salmonella host cell invasion emerged by acquisition of a mosaic of
RT separate genetic elements, including Salmonella pathogenicity island 1
RT (SPI1), SPI5, and sopE2.";
RL J. Bacteriol. 183:2348-2358(2001).
CC -!- FUNCTION: Converts phosphatidylinositol 3,4,5-trisphosphate (PtdIns
CC 3,4,5-P3) to PtdIns 3-P and prevents the transition of PtdIns 3-P to
CC PtdIns 3,5-P2. It is one of the known effectors injected by Salmonella
CC into the host cell and is required for invasion and for an efficient
CC generation and maintenance of Salmonella-containing vacuole (SVC).
CC Alteration of the phosphoinositide composition of the plasma membrane
CC causes membrane ruffling and actin cytoskeleton rearrangements. The
CC persistence of PtdIns 3-P diverts the SCV from the endocytic pathway
CC resulting in enlarged vesicles, which are essential to create a
CC favorable environment where Salmonella can replicate and avoid immune
CC defenses of the host cell (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 -!- DOMAIN: Contains the consensus sequence Cys-X(5)-Arg characteristic of
CC Mg-independent phosphatases.
CC -!- SIMILARITY: Belongs to the phosphatase IpgD/SopB family. {ECO:0000305}.
