Invasin
Invasin is a bacterial membrane protein (from Y.pseudotuberculosis) that binds tightly to beta-1-integrins found on the surface of many mamallian cells; interaction between invasin and beta-1-integrins induces the physical uptake of bacteria by mamallian cells via a Rac-1 mediated response (Wong & Isberg, 2005; PMID: 15694850)
Usage and Biology
Chris Anderson & colleagues have demonstrated that the display of invasin on E. coli allows invasin-mediated internalization by mammalian cells; such update does not require additional known adhesion molecules. Their work was done in E. coli MC1061, a fim+ strain, and CAMC600, a fim- strain (Andereson et al., 2005 PMID: 16330045). Inv+ E. coli can invade a broad range of tumor cells (epithelial, hepatocarcinoma, and osteosarcoma).
