Required for normal synthesis of the cell wall and alkaline pH-induced hypha formation. Random hydrolysis of (1->6)-alpha-D-mannosidic linkages in unbranched (1->6)-mannans. Induced by caspofungin. Expression is also regulated by SPF1. 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. N-mannosylated. Leads to decreased caspofungin sensitivity. Belongs to the glycosyl hydrolase 76 family.
