Differential roles of phosphatidylserine, PtdIns(4,5)P2, and PtdIns(3,4,5)P3 in plasma membrane targeting of C2 domains. Molecular dynamics simulation, membrane binding, and cell translocation studies of the PKCalpha C2 domain.

Abstract excerpt

Many cytosolic proteins are recruited to the plasma membrane (PM) during cell signaling and other cellular processes. Recent reports have indicated that phosphatidylserine (PS), phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P(2)), and phosphatidylinositol 3,4,5-trisphosphate (PtdIns(3,4,5)P(3)) that are present in the PM play important roles for their specific PM recruitment. To systematically analyze how...
