GPI-anchored protein involved in proper cell wall integrity. Does not seem to be directly involved in the synthesis of the cell wall. Required for normal virulence in a mouse model of disseminated candidiasis. Induced during cell wall regeneration. Expression is also increased under high-iron conditions. Repressed by the HAP43 transcription factor. Leads to hyperfilamentation, increased biofilm formation and reduced virulence in a mouse model of disseminated candidiasis. Leads also to increased susceptibility to antifungals (fluconazol, posaconazol or amphotericin B) that target the plasma membrane and to altered sensitivities to environmental (heat, osmotic and oxidative) stresses.
