GPI-anchored cell wall protein required for mating efficiency, biofilm formation, adhesion, filamentous growth, and oxidative stress tolerance. Involved in normal disseminated infection in a mouse systemic candidiasis model. localizes to the cell wall of hyphae. Expressed in hyphae. Regulated by the EFG1 and TUP1 transcription factors. 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 (By similarity).
