Hydrophilin which is essential to overcome the simple stress of the desiccation-rehydration process. Induced during cell wall regeneration and upon milbemycins A3 oxim derivative (A3Ox) treatment. Expression is also regulated by SSN6. 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). Belongs to the PGA14 family.
