Probable protein phosphatase that may function in abscisic acid (ABA) signaling. H2O + O-phospho-L-seryl-[protein] = L-seryl-[protein] + phosphate H2O + O-phospho-L-threonyl-[protein] = L-threonyl-[protein] + phosphate Binds 2 magnesium or manganese ions per subunit. Interacts with PYL9. Localizes predominantly in nucleus. Induced by abscisic acid (ABA). Plants overexpressing PP2C06 exhibit dramatically reduced fertility and severe pre-harvest sprouting. Belongs to the PP2C family. Truncated N-terminus.
