Component of the cell wall involved in virulence which plays a role in the relationship between C.albicans and the host. Up-regulated upon milbemycin A3 oxim derivative (A3Ox) treatment. 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 SRP1/TIP1 family.
