The yeast expression system is useful for determining PATs for PSD-95 and SNAP25b. (A, B) SEY6210 (wild type) cells harboring the pYU-PSD95 (PSD-95-9xMyc; A) or pAC-SNAP25b (9xMyc-SNAP25b; B) plasmid were transfected with the pAKNF314 (vector), pAKNF-AKR1 (3xFLAG-AKR1), pAKNF-AKR2 (3xFLAG-AKR2), pAKNF-SWF1 (3xFLAG-SWF1), pAKNF-ERF2 (3xFLAG-ERF2), pAKNF-PFA3 (3xFLAG-PFA3), pAKNF-PFA4 (3xFLAG-PFA4), pAKNF-PFA5 (3xFLAG-PFA5), pAKNF-DHHCx (3xFLAG-DHHCx, with x representing the DHHC number, x = 1–17, 19–22, and 24), or pLECF-DHHC18 (DHHC18-3xFLAG) plasmid. Total cell lysates were prepared and treated sequentially with NEM, hydroxylamine, and biotin-HPDP. (A) The biotinylated samples were subjected to immunoprecipitation with anti-Myc antibodies and detected either by streptavidin-HRP (top) or by immunoblotting with anti-Myc antibody (bottom). (B) The biotinylated samples were precipitated with immobilized avidin beads and detected by immunoblotting with anti-Myc antibody (top). The DHHC proteins in the total lysates were detected using immunoblotting with anti-Myc antibody (bottom). Each experiment was repeated three times, and representative results are shown. pal., palmitoylated; PSD, PSD-95; SNAP, SNAP25b.
