General annotation (Comments)
| Catalytic activity | A phosphoprotein + H2O = a protein + phosphate. |
| Cofactor | Binds 1 iron ion per subunit By similarity. Binds 1 manganese ion per subunit By similarity. |
| Subunit structure | PP2A consists of a common heterodimeric core enzyme, composed of a 36 kDa catalytic subunit (subunit C) and a 65 kDa constant regulatory subunit (subunit A), that associates with a variety of regulatory subunits such as subunits B (the R2/B/PR55/B55, R3/B''/PR72/PR130/PR59 and R5/B'/B56 families) By similarity. |
| Subcellular location | |
| Sequence similarities | Belongs to the PPP phosphatase family. PP-2A subfamily. |
| Sequence caution | The sequence CAB68188.1 differs from that shown. Reason: Erroneous gene model prediction. |
