Inhibition of PH
binding. Inhibition of PHGrp1 and PHAkt (10 μM) binding to liposomes containing PtdIns(3,4)P2 by myo-inositol pentakisphosphates (100 μM). Percent inhibition is plotted on the y-axis for the different IP5 isomers. Percent inhibition values are shown above the bars. Error bars represent +/- standard error of mean (SEM).
