GPI-anchored cell wall protein involved in cell wall organization, hyphal growth, as well as in host-fungal interaction and virulence. Plays a role in adherence to plastic and to host epithelial cells. Promotes the tissue fungal burden during murine vaginal candidiasis. Increases also susceptibility to neutrophil-mediated killing. Furthermore, contributes to the severity of hematogenously disseminated candidiasis in normal mice, but not in neutropenic mice. Repressed by HAP43 and in absence of GOA1. 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. Leads to decreased adherence of germ tubes to plastic and epithelial cells, but not endothelial cells. Belongs to the HYR1/IFF family.
