Involved in cell wall, plasma membrane, and cytoskeletal organization. Plays a role in endocytosis and hyphal morphogenesis. Required to restrict septin proteins to the bud neck and prevents intracellular growth of cell wall. Contributes to secretion, biofilm formation, and macrophage killing. Essential for resistance to stressful conditions and for invasive growth and virulence. Localizes at eisosomes, structures which colocalize with sites of protein and lipid endocytosis. Induced by fluconazole and down-regulated in absence of GOA1. Leads to defective tolerance to cell wall stress and antifungal agents targeting cell wall components, defective plasma membrane structure, defective endocytosis, impaired lipase secretion, SAP2 over-production, increased adherence, aberrant biofilm formation, defective macrophage killing, and decreased virulence in a mouse infection model. Belongs to the SUR7 family.
