Secreted effector that suppresses host plant glucan elicitor-mediated defense responses (Probable). Targets host endoglucanases and inhibits the endoglucanase-mediated release of elicitor-active glucan oligosaccharides from P.sojae cell walls (Probable). Belongs to the peptidase S1 family. None of the predicted glucanase inhibitor proteins (GIPS) has an intact catalytic triad, therefore, GIPs are proteolytically inactive.
