Serine/threonine-protein phosphatase that plays an important role in controlling colony morphology, filament extension and agar invasion. Down-regulates expression of NRG1 and affects the expression of multiple filament-specific transcripts in response to serum and 37 degrees Celsius. Plays a crucial role in virulence in a mouse model of systemic candidiasis. H2O + O-phospho-L-seryl-[protein] = L-seryl-[protein] + phosphate H2O + O-phospho-L-threonyl-[protein] = L-threonyl-[protein] + phosphate Binds 2 manganese ions per subunit. Inhibited by okadaic acid, a specific inhibitor of serine/threonine phosphatases of types 1, 2A and 2B. Leads to defect in morphogenesis and reduced virulence. Belongs to the PPP phosphatase family. PP-2A subfamily.
