Secreted effector that acts as a RNA silencing suppressor, probably by inhibiting the biogenesis of small RNAs in the host plant, to manipulate host immune responses and promote Phytophthora infection. Expression is specifically induced early in the infection process, in contact with host tissue. The RxLR-dEER motif acts to carry the protein into the host cell cytoplasm through binding to cell surface phosphatidylinositol-3-phosphate. Belongs to the RxLR effector family.
