| Outline of Final Research Achievements |
Two major objectives of this research project are as follows. (1) Development of a new two-dimensional in-gel phosphatase assay. (2) Elucidation of the regulatory mechanisms of PPM family phosphatases including CaM-kinase phosphatase (CaMKP) and nuclear CaMKP (CaMKP-N). In this project, we have successfully developed a unique two-dimensional in-gel phosphatase assay using fluorogenic substrate, 4-methylumbelliferyl phosphate (MUP). Futhermore, we clarified the regulatory mechanisms of cellular localization of CaMKP-N through proteolytic processing and found a new anchoring protein, protocadherin gamma subfamily C5, that regulate CaMKP activity in vivo.
