GPI-anchored cell wall protein involved in cell wall organization, hyphal growth, as well as in host-fungal interaction and virulence. Opaque-specific transcript. Repressed by HAP43 and induced by macrophages. The GPI-anchor is attached to the protein in the endoplasmic reticulum and serves to target the protein to the cell surface. There, the glucosamine-inositol phospholipid moiety is cleaved off and the GPI-modified mannoprotein is covalently attached via its lipidless GPI glycan remnant to the 1,6-beta-glucan of the outer cell wall layer. Belongs to the HYR1/IFF family.
