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. Has the canonical EER motif, but lacks the canonical translocation motif RxLR, which characterizes most oomycete effectors identified so far. Belongs to the RxLR effector family.
