Secreted effector that confers enhanced plant susceptibility during both compatible and incompatible interactions between the pathogen and its host (PubMed:22072967, PubMed:21914011). Promotes the sexual reproduction of the pathogen in the plant host (PubMed:21914011). Interacts with host A.thaliana At1G14340. Localizes to the membrane around haustoria also called extrahaustorial membrane (EHM) at early and late stages of infection. The RxLR-dEER motif is required for the delivery of the effector to the host cell cytoplasm but does not bind phosphatidylinositol monophosphates. The C-terminal region (residues 247 to 269) consists of one W motif, a conserved motif found in already well characterized effectors that may be involved in the interaction with host proteins. Belongs to the RxLR effector family.
