Effector that suppresses plant defense responses during the early stages of pathogen infection. Suppresses cell death induced by effectors and PAMPs in plant hosts (PubMed:21653195, PubMed:27256489). Avh262 stabilizes endoplasmic reticulum (ER)-luminal binding immunoglobulin proteins (BiPs), which act as negative regulators of plant resistance to Phytophthora. By stabilizing BiPs, Avh262 suppresses ER stress-triggered cell death and facilitates Phytophthora infection (PubMed:27256489). Interacts with host plant ER-luminal binding immunoglobulin proteins (BiPs) such as soybean BiP1, BiP2, BiP3 and BiP4. Residues 60 to 82 are required for the interaction with host plant binding immunoglobulin proteins (BiPs) and subsequent virulence. The RxLR-dEER motif acts to carry the protein into the host cell cytoplasm through binding to cell surface phosphatidylinositol-3-phosphate. Leads to reduced virulence on etiolated soybean seedlings. Belongs to the RxLR effector family.
