Effector that binds transcription regulators in the host plant to suppress the host's innate immune response (PubMed:29757140). Inhibits the host plant transcription regulators CBP60G and SARD1 (PubMed:29757140). Interacts with A.thaliana CBP60G; the interaction is direct (PubMed:29757140). Interacts with A.thaliana SARD1 (PubMed:29757140). Interacts with G.hirsutum CBP60B (PubMed:29757140). Expression is induced by plant roots. Decreases virulence in A.thaliana and G.hirsutum.
