Western blot analysis of Methyl-PP2A alpha (Leu309) in two yeast strains using a Methyl-PP2A alpha (Leu309) monoclonal antibody (MA5-18072). Native cultures from yeast deletion strains expressing the HA-tagged PP2AC (PPH21) were subjected to IP against the HA tag: strain PPE1-delta (left) which lacks the PP2A methylesterase (PPE1) and accumulates methylated PPH21, and PPM1-delta which lacks the PP2A methyltransferase and contains no methylated PPH21. The lysates were boiled in Laemmli buffer, separated by SDS-PAGE and transfered to a nitrocellulose membrane. Lane 5 shows a control incubated with an anti-HA tag monoclonal antibody.

This antibody recognizes the C-terminal methylated form of PP2A (C subunit). The c-terminal sequence, as well as the carboxy-methylation, is 100% conserved in human, mouse and yeast.
Western blot results show a band at 36 kDa, which matches the predicted molecular weight.
The product of this gene belongs to the phosphatase 2 regulatory subunit B family. Protein phosphatase 2 is one of the four major Ser/Thr phosphatases, and it is implicated in the negative control of cell growth and division. It consists of a common heteromeric core enzyme, which is composed of a catalytic subunit and a constant regulatory subunit, that associates with a variety of regulatory subunits. The B regulatory subunit might modulate substrate selectivity and catalytic activity. This gene encodes a gamma isoform of the regulatory subunit B55 subfamily. Alternatively spliced transcript variants encoding different isoforms have been identified.
