Outline of Final Research Achievements

We have obtained the results regarding CaMKK-mediated intracellular signal transduction as follows; (1) CaMKKβ is phosphorylated at Thr144 in HeLa cells upon stimulation with isoproterenol, indicating the regulatory phosphorylation of CaMKKβ by cAMP-mediated signaling. (2) CaMKKβ is also rapidly dephosphorylated in the cells suggesting the dynamic regulation of CaMKKβ through phosphorylation/dephosphorylation. (3) We have succeeded to develop a novel CaMKK inhibitor (TIM-063) and an inactive analogue (TIM-062) which could be useful for evaluating the physiological roles of CaMKK-mediated signaling pathways.

Academic Significance and Societal Importance of the Research Achievements

Ca2+/Calmodulin(CaM)依存性プロテインキナーゼ活性化キナーゼ(CaMKK)は、CaMキナーゼⅠやCaMキナーゼⅣ、5’-AMP活性化キナーゼ(AMPK)をリン酸化依存的に活性化し、遺伝子発現や神経発生、代謝調節に至る多様な細胞内Ca2+に応答した生理機能を調節するとともに、前立腺がん増殖などの疾患との関連も示唆されている。本研究により、CaMKKの詳細な細胞内調節機構を解明し、正常および病態におけるCaMKKの役割の一端を解明するとともに、治療薬の開発を目指した新たなCaMKK阻害剤の創製に成功した。
