Your Input:
sseIGifsy-2 prophage putative type III secreted protein; Effector proteins function to alter host cell physiology and promote bacterial survival in host tissues. This protein is required to maintain a long-term chronic systemic infection in mice. It inhibits normal cell migration of primary macrophages and dendritic cells, by a mechanism that involves interaction with the host factor IQGAP1, an important regulator of the cytoskeleton and cell migration. Also accelerates the systemic spread of infection from the gastrointestinal tract to the bloodstream, probably by interacting with host TRIP6. (322 aa)
sopBPathogenicity island encoded protein: SPI5; Converts phosphatidylinositol 3,4,5-trisphosphate (PtdIns 3,4,5-P3) to PtdIns 3-P and prevents the transition of PtdIns 3-P to PtdIns 3,5-P2. It is one of the known effectors injected by Salmonella into the host cell and is required for invasion and for an efficient generation and maintenance of Salmonella-containing vacuole (SVC). Alteration of the phosphoinositide composition of the plasma membrane causes membrane ruffling and actin cytoskeleton rearrangements.

This protein is required for endosomal tubulation and negatively regulates the formation of Salmonella-induced filaments (Sifs) in epithelial cells. Has both deacylase and esterification activities in vitro, but esterification is probably the dominant activity in host cells. Significantly contributes to cholesterol esterification, which reduces cellular cholesterol in cells and abrogates the ability of SifA to associate with cholesterol and LAMP-1 v [...] (408 aa)

Potentiates SipC activity; both are required for an efficient bacterial internalization. In vitro, forms a complex with host cell protein T-plastin increasing actin bundling. It inhibits ADF/cofilin-directed depolymerization both by preventing binding of ADF and cofilin and by displacing them from F-actin. Also protects F-actin from gelsolin-directed severing and reanneals gelsolin-severed F-actin fragments; [...] (685 aa)
sipDCell invasion protein; Required for translocation of effector proteins via the type III secretion system SPI-1, which is essential for an efficient bacterial internalization. Probably acts by modulating the secretion of SipA, SipB, and SipC. (343 aa)

Along with SipC, is necessary for the transfer of other effector proteins into the host cell. Induces macrophage apoptosis either by binding and activating the proapoptotic enzyme caspase-1 (caspase-1 dependent), resulting in the release of interleukin-1 beta active form, or by disrupting mitochondria and inducing autophagy (caspase-1 independent). The former is dependent of its membrane-fusion activity. The SipBC complex, in association with its chape [...] (593 aa)
