Abstract:
Pathogenic species of the genus Yersinia suppress and reorient the immune system to infect lymphatic tissues, inner organs and at times also the vasculature. For this purpose yersiniae employ a type III secretion system to translocate effector proteins (Yersinia outer proteins; Yops) into immune cells. Yops often exert unique biochemical activities for modulating the activity of Rho GTP-binding proteins, focal adhesion proteins, inflammatory pathways and cell survival/apoptosis. In this review we will put emphasis on the biochemistry, cell- and infection biology of Yersinia effector Yops.
