Biphasic Regulation of Yes-associated Protein (YAP) Cellular Localization, Phosphorylation, and Activity by G Protein-coupled Receptor Agonists in Intestinal Epithelial Cells: A NOVEL ROLE FOR PROTEIN KINASE D (PKD).
Journal of Biological Chemistry 2016 August 20
We examined the regulation of Yes-associated protein (YAP) localization, phosphorylation, and transcriptional activity in intestinal epithelial cells. Our results show that stimulation of intestinal epithelial IEC-18 cells with the G protein-coupled receptor (GPCR) agonist angiotensin II, a potent mitogen for these cells, induced rapid translocation of YAP from the nucleus to the cytoplasm (within 15 min) and a concomitant increase in YAP phosphorylation at Ser(127) and Ser(397) Angiotensin II elicited YAP phosphorylation and cytoplasmic accumulation in a dose-dependent manner (ED50 = 0.3 nm). Similar YAP responses were provoked by stimulation with vasopressin or serum. Treatment of the cells with the protein kinase D (PKD) family inhibitors CRT0066101 and kb NB 142-70 prevented the increase in YAP phosphorylation on Ser(127) and Ser(397) via Lats2, YAP cytoplasmic accumulation, and increase in the mRNA levels of YAP/TEAD-regulated genes (Ctgf and Areg). Furthermore, siRNA-mediated knockdown of PKD1, PKD2, and PKD3 markedly attenuated YAP nuclear-cytoplasmic shuttling, phosphorylation at Ser(127), and induction of Ctgf and Areg expression in response to GPCR activation. These results identify a novel role for the PKD family in the control of biphasic localization, phosphorylation, and transcriptional activity of YAP in intestinal epithelial cells. In turn, YAP and TAZ are necessary for the stimulation of the proliferative response of intestinal epithelial cells to GPCR agonists that act via PKD. The discovery of interaction between YAP and PKD pathways identifies a novel cross-talk in signal transduction and demonstrates, for the first time, that the PKDs feed into the YAP pathway.
