| Outline of Final Research Achievements |
Phosphodiesterase (PDE) regulates intracellular concentrations by degrading enzymes of intracellular signal transduction substances cAMP and cGMP, and is involved in various physiological actions. There are 11 types of isozymes from PDE1 to PDE11 in PDE. We have reported for the first time in the world that PDE2, one of the PDE isozymes, is associated with invasion. It is considered that one amino acid of the PDE2 protein is changed by mutation of a specific site of the PDE2 gene., and as a result, the intracellular localization of the PDE2 protein is changed. In this study, we found that the expression level of mutants may regulate localization and invasion.
