1 We show that the PKC-induced effects strongly depend on PIP2 levels in the membrane. Phosphatidylinositol 4,5-Diphosphate proline rich transmembrane protein 2 Homo sapiens
2 At the same time, we show that PKC destabilizes Kir3/PIP2 interactions and enhances the effects of PIP2 depletion on channel activity. Phosphatidylinositol 4,5-Diphosphate proline rich transmembrane protein 2 Homo sapiens
3 We also show that stabilization of Kir3/PIP2 interactions by Gbetagamma attenuates both PKC and Gq-mediated current inhibition, suggesting that diverse pathways regulate Kir3 activity through modulation of channel interactions with PIP2. Phosphatidylinositol 4,5-Diphosphate proline rich transmembrane protein 2 Homo sapiens
