GPI-anchored cell wall protein that may be involved in cell wall organization, hyphal growth, as well as in virulence. Induced during yeast to hyphae transition, during biofilm formation, during oralpharyngeal candidasis, and in response to serum. Regulated BY FLO8, NRG1, RFG1, RGT1, TUP1, TSA1, and UME6. 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 IHD1 family.
