== Function ==
[[http://www.uniprot.org/uniprot/SOPD2_SALTY SOPD2_SALTY]] Effector proteins function to alter host cell physiology and promote bacterial survival in host tissues. Contributes to the formation of Salmonella-induced filaments (Sifs) in infected epithelial cells and to replication in macrophages.<ref>PMID:15554961</ref>

== Publication Abstract from PubMed ==
Intracellular bacterial pathogens of a diverse nature share the ability to evade host immunity by impairing trafficking of endocytic cargo to lysosomes for degradation, a process that is poorly understood. Here, we show that the Salmonella enterica type 3 secreted effector SopD2 mediates this process by binding the host regulatory GTPase Rab7 and inhibiting its nucleotide exchange. Consequently, this limits Rab7 interaction with its dynein- and kinesin-binding effectors RILP and FYCO1 and thereby disrupts host-driven regulation of microtubule motors. Our study identifies a bacterial effector capable of directly binding and thereby modulating Rab7 activity and a mechanism of endocytic trafficking disruption that may provide insight into the pathogenesis of other bacteria. Additionally, we provide a powerful tool for the study of Rab7 function, and a potential therapeutic target.
