WebSep 1, 2014 · Granuphilin contains two C2 domains, C2A and C2B, that interact with the plasma membrane lipid phosphatidylinositol-(4,5)-bisphosphate [PI(4,5)P 2]. The goal of this study was to determine membrane-binding mechanisms, affinities, and kinetics of both granuphilin C2 domains using fluorescence spectroscopic techniques. NMR analysis of the granuphilin-C2A domain interacting with PI(4,5)P2-nanodisc demonstrates that, besides residues within the concave groove that are responsible for PI(4,5)P2 head group binding, the strand β5 was also affected. This region may be involved in direct binding to membrane and/or undergo conformation changes upon membrane binding.
