Component of the cell wall involved in virulence. Does not seem to have a major role in maintaining cell wall integrity but plays a role in the relationship between C.albicans and the host. Down-regulated during yeast-to-hyphal transition and by fluconazole. Induced during cell wall regeneration following protoplasting and highly overexpressed after treatment with micafungin. 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. O-glycosylated by PMT1. Leads to a significant reduction of cell wall mannan and to decreased virulence with a diminished induction of host pro-inflammatory cytokines. Belongs to the SRP1/TIP1 family.
