Overduin and colleagues present the NMR structures of free, micelle and PtdIns(4)P-bound FAPP1-PH domain. The micelle-bound structure reveals how its prominent wedge independently tubulates Golgi membranes by leaflet penetration. A hydrophobic element inserts into and bends membranes, and is conserved in pleckstrin homology domains of CERT and OSBP proteins.
