A Long QT Mutation Substitutes Cholesterol for Phosphatidylinositol-4,5-Bisphosphate in KCNQ1 Channel Regulation

INTRODUCTION: Phosphatidylinositol-4,5-bisphosphate (PIP(2)) is a cofactor necessary for the activity of KCNQ1 channels. Some Long QT mutations of KCNQ1, including R243H, R539W and R555C have been shown to decrease KCNQ1 interaction with PIP(2). A previous study suggested that R539W is paradoxically...
