Secreted effector involved in P.mirabilis colonization of host plants (Probable). May perturb the signaling of cell death associated with plant immunity, via interaction with a host MAP kinase (Probable). The RxLR-dEER motif acts to carry the protein into the host cell cytoplasm through binding to cell surface phosphatidylinositol-3-phosphate. The WY domain contains 3 alpha-helices and is required for the interaction with a host MAP kinase. Belongs to the RxLR effector family.
