This family represents the C-terminal guanine nucleotide exchange factor (GEF) domain of SopE. Salmonella typhimurium employs a type III secretion system to inject bacterial toxins into the host cell cytosol. These toxins transiently activate Rho family GTP-binding protein-dependent signaling cascades to induce cytoskeletal rearrangements. SopE, can activate Cdc42, an essential component of the host cellular signaling cascade, in a Dbl-like fashion despite its lack of sequence similarity to Dbl-like proteins, the Rho-specific eukaryotic guanine nucleotide exchange factors [1].
