Plays role in broad-spectrum disease resistance. Probably has no oxalate oxidase activity even if the active site is conserved. Oligomer (believed to be a pentamer but probably hexamer). Member of the 12 germin-like protein gene cluster located on chromosome 8 in the major-effect quantitative trait loci (QTL) for fungal blast resistance. Partial suppression of the 12 germin-like protein genes increases susceptibility to the fungal pathogens causing rice blast and sheath blight diseases. Belongs to the germin family.
