Secreted effector that inhibits stress-induced relocalization of the transcription factor NAC069 to the nucleus, thus affecting its broad role in abiotic and biotic stress responses. Interacts with host transcription factor NAC069. Localizes to unidentified ring-like structures of varying size within the host cell. Has the canonical translocation RxLR motif, but lacks the canonical EER motif, which characterizes most oomycete effectors identified so far. Belongs to the RxLR effector family.
