Article Title: Structure and lipid-binding properties of the kindlin-3 pleckstrin homology domain
doi: 10.1042/BCJ20160791
Figure Lengend Snippet: ( A ) Schematic representation of SPR experiments with the immobilised lipid headgroup as the ligand and the PH domain as the analyte. ( B ) SPR measurements of the kindlin-3 PH domain WT and mutants with immobilised PtdIns(4,5)P 2 and PtdIns(3,4,5)P 3 , respectively. On the left in each case, we show the background-subtracted raw sensogram data for the WT protein, while on the right we show binding saturation curves for WT, K363A K367A and IPRR insertion mutants. The highest concentration used is given on each set of sensogram curves; subsequent binding profiles derive from a series of twofold dilutions.
Article Snippet: POPC and POPE (1-palmitoyl-2-oleoyl- sn -glycero-3-phosphoethanolamine) were purchased from Avanti Polar Lipids, and PtdIns(4,5)P 2 (P-4516), PtdIns(3,4,5)P 3 (P-3924), and Ins(1,3,4,5)P 4 (Q-1345) were purchased from Echelon Biosciences.
