| Outline of Final Research Achievements |
Aquaporins which are intrinsic membrane proteins functioning as a water channel permeable to water and glycerol. All aquaporin molecules expressing in cells do not always exist in a cell membrane, but the trafficking of aquaporins in a cell are controlled to move between the cell membrane and inside the cell as necessary. We found that the movement of aquaporin 3 from inside to membrane was regulated by protein kinase C and that from membrane to inside was done by protein kinase B (Akt). Phosphorylation of Thr237 and Ser275 in aquaporin 3 was confirmed to be necessary to move from inside the cell to cell membrane.
We investigated natural compounds which triggered the trafficking of aquaporins. Eugenol which is a component of magnolia flower derived from Magnolia salicifolia was found to promote the trafficking of aquaporin 3 from inside to membrane accompanying the phosphorylation of protein kinase C.
