Secreted effector that acts as an elicitor of hypersensitive response (HR) specifically on plants carrying defense protein R10 (PubMed:11768540). Enhances P.infestans colonization of Nicotiana benthamiana leaves (PubMed:30329083). Expression is induced during host plant infection. The RxLR-dEER motif acts to carry the protein into the host cell cytoplasm through binding to cell surface phosphatidylinositol-3-phosphate. Leads to gain of virulence on potato lines carrying defense protein R10. Belongs to the RxLR effector family.
