Product Description

PSD-95 is a member of proteins located at a specialized postsynaptic membrane region, called the postsynaptic density (PSD). PSD-95 is the most abundant scaffold protein specifically enriched in the PSD. It contains three PDZ domains, an SH3 domain and a guanylate kinase (GuK)-like domain. Through its PDZ domains, PSD-95 assembles various synaptic components at the PSD including intracellular signaling molecules (e.g. SynGAP and kalirin-7), ion channels (e.g. stargazin/AMPA receptors [AMPARs] and NMDA receptors) and cell adhesion molecules (e.g. neuroligin). PSD-95 plays a primary role in synaptic development and maturation and is regulated by palmitoylation at its N-terminal cysteine residues leading to its postsynaptic targeting. Palmitoylation of PSD-95 is triggered by DHHC2, a plasma membrane-inserted palmitoylating enzyme. Palmitoylated PSD-95 is almost exclusively localized at excitatory synapses in neurons.

Palmitoylated PSD95 is detected by immunocytochemistry using anti-PSD-95 (palmitoylated), mAb (rec.) (PF11) (Prod. No AG-27B-0021).<br /> <b>Method:</b> HeLa cells were cotransfected with DHHC2 (palmitoylating enzyme) + PSD95-GFP (A) or DHHC2 (palmitoylating enzyme) alone (B). Cells in "B" were fixed with paraformaldehyde (3%), permeablized in PBS+ BSA 0.2 % + Saponin 0.05 % and incubated with anti-PSD-95 (palmitoylated), mAb (rec.) (PF11) (1µg/ml in PBS-BSA-Saponin).  After incubation for 30min at RT and several washes in PBS, cells are treated with a goat anti-human (ATTO488) antibody in PBS-BSA-Saponin  for 30min at RT, washed and mounted in Moewiol. Nuclei are stained with DAPI. Merge image is shown at the right. <i>Picture courtesy of  Dr. Moutel, Dr. Franck Perez Lab, Curie Institute, Paris.</i>
