L-PS was sonicated in 50 mM Tris-HCl at 0°C prior to use. After incubation at 0°C for 2 h, the mixture was diluted with cold 0.5 % DMSO (2.5 mL) then filtered through a glass-fiber filter (Whatman GF/B), which had been pretreated with 0.3% polyethyleneimine for 1 h. The filter was washed four times with 2 mL of cold 0.5% DMSO. The radioactivity of each filter was counted in a scintillation vial with 5 mL of scintillator (Clear-sol I from NACALAI TESQUE) using a liquid scintillation counter

    • 3) was used instead of 1f. The docking model was constructed in the Affinity module of the INSIGHT II molecular program developed by MSI (now succeeded by Accelrys, San Diego). The first binding placement of isobenzofuranone within the PKCδ C1B domain was made by superimposing the molecule on the critical functional groups of phorbol 13-acetate. We constructed a 'grid', which is partitioned into bulk (nonflexible) and movable atoms of the ligand/receptor system; interactions among bulk atoms are approximated by using the accurate and efficient molecular mechanical/grid (MM/Grid) method, while interactions among movable atoms are treated using a full force field representation. The grid was defined by the amino acid residues within 6 Å around the isobenzofuranone. The binding model was made using a Monte Carlo type procedure to search both conformational and Cartesian space
