RESUMO

Type III secreted Sop protein effectors are delivered into target eukaryotic cells and elicit cellular responses underlying Salmonella pathogenicity. In this work, we have identified another secreted protein, SopE2, and showed that SopE2 is an important invasion-associated effector. SopE2 is encoded by the sopE2 gene which is present and conserved in pathogenic strains of Salmonella. SopE2 is highly homologous to SopE, a protein encoded by a gene within a temperate bacteriophage and present in only some pathogenic strains.
