  • ICC staining of PSD95 in N2A cells (green). Formalin fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 10 minutes at room temperature and blocked with 1% Blocker BSA for 15 minutes at room temperature. Cells were probed with the primary antibody (ET1602-20, 1/50) for 1 hour at room temperature, washed with PBS. Alexa Fluor®488 Goat anti-Rabbit IgG was used as the secondary antibody at 1/1,000 dilution. The nuclear counter stain is DAPI (blue).
  • ICC staining of PSD95 in SH-SY5Y cells (green). Formalin fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 10 minutes at room temperature and blocked with 1% Blocker BSA for 15 minutes at room temperature. Cells were probed with the primary antibody (ET1602-20, 1/50) for 1 hour at room temperature, washed with PBS. Alexa Fluor®488 Goat anti-Rabbit IgG was used as the secondary antibody at 1/1,000 dilution. The nuclear counter stain is DAPI (blue).
  • Immunohistochemical analysis of paraffin-embedded rat brain tissue using anti-PSD95 antibody. The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 8.0-8.4) for 20 minutes.The tissues were blocked in 5% BSA for 30 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (ET1602-20, 1/200) for 30 minutes at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.
  • Immunohistochemical analysis of paraffin-embedded mouse cerebullum tissue using anti-PSD95 antibody. The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 8.0-8.4) for 20 minutes.The tissues were blocked in 5% BSA for 30 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (ET1602-20, 1/200) for 30 minutes at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.
  • Flow cytometric analysis of PSD95 was done on SH-SY5Y cells. The cells were fixed, permeabilized and stained with the primary antibody (ET1602-20, 1/50) (blue). After incubation of the primary antibody at room temperature for an hour, the cells were stained with a Alexa Fluor 488-conjugated Goat anti-Rabbit IgG Secondary antibody at 1/1000 dilution for 30 minutes.Unlabelled sample was used as a control (cells without incubation with primary antibody; red).

TISSUE SPECIFICITY

Brain.

POST-TRANSLATIONAL MODIFICATION

Palmitoylated. Palmitoylation is required for targeting to postsynaptic density, plasma membrane and synapses (By similarity). Palmitoylation by ZDHHC2 occurs when the synaptic activity decreases and induces DLG4 synaptic clustering (By similarity). Palmitoylation may play a role in glutamate receptor GRIA1 synapse clustering (By similarity). Depalmitoylated by ABHD17A and ABHD17B and to a lesser extent by ABHD17C, ABHD12, ABHD13, LYPLA1 and LYPLA2. Undergoes rapid synaptic palmitoylation/depalmitoylation cycles during neuronal development which slow down in mature neurons (By similarity).; Ubiquitinated by MDM2 in response to NMDA receptor activation, leading to proteasome-mediated degradation of DLG4 which is required for AMPA receptor endocytosis.

SUBCELLULAR LOCATION

Cell membrane, Cell junction

FUNCTION

The Drosophila discs large (dlg) tumor suppressor gene was first identified in Drosophila through genetic analysis of germline mutations. Several mammalian homologs were subsequently identified and categorized into a protein family termed MAGUK (membrane-associated guanylate kinase homolog). Human homologs of dlg include hdlg-1 (rat SAP 97) and NE-dlg (neuronal and endocrine dlg). The rat synaptic protein PSD-95 (also designated SAP 90) also shares homology with these proteins. MAGUKs are localized at the membrane-cytoskeleton interface and contain several distinct domains which suggest a role for these proteins in intracellular signal transduction. Interaction of hdlg-1 and NE-dlg with the tumor suppresor protein APC suggest that MAGUK proteins may also play a role in regulation of growth.
