Protein phosphatase that acts as a modulator of pkcA/mpkA activity involved in the cell wall integrity pathway (PubMed:25911225). Plays an important role in regulation of adhesion, cell wall integrity, biofilm formation, and virulence (PubMed:25911225). H2O + O-phospho-L-threonyl-[protein] = L-threonyl-[protein] + phosphate Binds 2 manganese ions per subunit. Leads to decreased mpkA phosphorylation levels, increased sensitivity to cell wall-damaging agents, increased levels of beta-(1,3)-glucan and chitin, impaired in biofilm formation, and decreased protein kinase C activity (PubMed:25911225). Increases also sensitivity to several metals and ions, such as MnCl(2), CaCl(2), and LiCl, but it is more resistant to ZnSO(4) (PubMed:25911225). Impeairs the virulencein a murine model of invasive pulmonary aspergillosis and induces an augmented tumor necrosis factor alpha response in mouse macrophages (PubMed:25911225). Belongs to the PPP phosphatase family. PP-6 (PP-V) subfamily.
