Cell wall protein which contributes to cell wall synthesis and is important for acquiring normal surface properties. Required for virulence in a mouse infection model. Covalently-linked GPI-modified cell wall protein (GPI-CWP). Induced by caspofungin, tunicamycin, during chlamydospore formation and during cell wall regeneration following protoplasting. Repressed by NRG1 and TUP1. Also regulated by TSA1. 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 increased sensitivity to Congo red, Calcofluor white, and zymolyase, delayed filamentation, a higher surface hydrophobicity, increased adherence and flocculation; as well as to a diminished ability of protoplasts to recover their cell wall.
