| Outline of Final Research Achievements |
Endosome is a multifunctional platform through the emission and the regulation of a variety of signal transduction pathways. However, the relationship between signaling dynamics and cell function via the endosomes in living cells has yet to be analyzed in detail. In this study, we demonstrated that angiotensin II (AII) type 2 receptor (AT2R) negatively regulates type 1 receptor (AT1R)-signaling through a series of events including heterodimerization of AT1R and AT2R, internalization via endocytosis of the complex, change in the molecular orientation of receptors in the complex. We also clarified that activation of both receptors and and phosphorylation of serine residues at the C-terminus of AT2R by protein kinase C (PKC) are indispensable for this function.
