Lee SF, Kelly M, McAlister A, Luck SN, Garcia EL, Hall RA, Robins-Browne RM, Frankel G, Hartland ELet al., 2008, A C-terminal class IPDZ binding motif of EspI/NIeA modulates the virulence of attaching and effacing Escherichia coli and Citrobacter rodentium, CELL MICROBIOL, Vol: 10, Pages: 499-513, ISSN: 1462-5814

Enteropathogenic Escherichia coli induces characteristic attaching-effacing (A/E) lesions on the intestinal mucosa during infection. The locus of enterocyte effacement is essential for A/E lesion formation and encodes a type III secretion system that translocates multiple effector proteins into the host cell. Following translocation, EspI/NIeA localizes to the Golgi. Using the yeast two-hybrid system (Y2HS) and PSD-95/Disk-large/ZO-1 (PDZ)-domain protein array overlays, we identified 15 putative host-interacting partners of Espl. All but two of the target proteins contained PDZ domains. Examination of the EspI amino acid sequence revealed a C-terminal consensus class I PDZ binding motif. Deletion of the last 7 amino acids of EspI to generate EspI(Delta C7) abrogated the Y2HS interaction between EspI and 5 of the 6 putative host cell target proteins tested. Deletion of the EspI PDZ binding motif also resulted in delayed trafficking of EspI to the Golgi. Using a mouse model of infection, we showed that Citrobacter rodentium expressing truncated EspI(Delta C7) was attenuated when in competition with C. rodentium expressing full-length EspI. Overall, these results suggested that Espl may modulate the virulence of A/E pathogens by binding host PDZ-domain proteins.
