100 ul in 10 mM HEPES (pH 7.5), 150 mM NaCl, 100 ug per ml BSA and 50% glycerol. Adequate amount of material to conduct 10-mini Western Blots.
Peptide corresponding to amino acid residues from the N-terminal region of rat PSD-95, conjugated to keyhole limpet hemocyanin (KLH).
Immunogen Information
Synthetic peptide corresponding to amino acid residues from the N-terminal region conjugated to KLH
Immunogen Species
Reactivity Assumed Based on 100% Sequence Homology
Bovine, human, mouse, non-human primates and zebra fish
Species Reactivity Note
The antibody has been directly tested for reactivity in Western blots in rat and mouse tissues. It is anticipated that the antibody will also work with bovine, human, non-human primates and zebra fish tissues based on the fact that these species have 100% homology with the amino acid sequence used as antigen.
Biological Significance
PSD-95 is a very prominent component of the postsynaptic densities of synapses. It contains three PDZ domains which play key roles in its interactions with other proteins in the synapse. It has been proposed that these PDZ domains organize glutamate receptors and their associated signaling proteins and determine the size and strength of synapses (Kim and Sheng, 2004). Recent work suggests that interaction of the NMDAR with PSD-95 via these PDZ domains can be regulated by phosphorylation (Chung et al., 2004).
Preparation and Storage
Store at -20 degree C; stable for at least one year.
Other Notes
Small volumes of anti-DLG4 antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

NCBI Summary for DLG4
a molecular scaffolding protein that binds and clusters N-methyl-D-aspartate receptors at neuronal synapses; may be involved in guanine nucleotide-mediated signal transduction pathway [RGD, Feb 2006]
UniProt Comments for DLG4
Function: Interacts with the cytoplasmic tail of NMDA receptor subunits and shaker-type potassium channels. Required for synaptic plasticity associated with NMDA receptor signaling. Overexpression or depletion of DLG4 changes the ratio of excitatory to inhibitory synapses in hippocampal neurons. May reduce the amplitude of ASIC3 acid-evoked currents by retaining the channel intracellularly. May regulate the intracellular trafficking of ADR1B. Ref.17 Ref.19 Ref.27

Subunit structure: Interacts through its PDZ domains with ANO2 and NETO1. Interacts through its first two PDZ domains with GRIN2A, GRIN2B, GRIN2C, GRIN2D, ASIC3, certain splice forms of GRIN1, KCND2, CXADR, SYNGAP1, KCNA1, KCNA2, KCNA3, KCNA4, ERBB4, LRRC4; LRRC4B and SEMA4C. Interacts through its first PDZ domain with GRIK2, KCNA4 and CRIPT. Interacts through its second PDZ domain with the PDZ domain of NOS1 or the C-terminus of CAPON. Interacts through its third PDZ domain with NLGN1 and CRIPT, and probably with NLGN2 and NLGN3. Interacts through its guanylate kinase-like domain with DLGAP1/GKAP, DLGAP2, DLGAP3, DLGAP4, MAP1A, BEGAIN, SIPA1L1 and KIF13B. Isoform 2 interacts through an L27 domain with HGS/HRS and the first L27 domain of CASK. Interacts with ADR1B, ANKS1B and PRR7. May interact with HTR2A. Interacts with ADAM22, KLHL17 and LGI1. Interacts with FRMPD4 (via C-terminus). Interacts with LRFN1, LRFN2 and LRFN4, but not with LRFN3 nor LRFN5. Interacts (via N-terminus tandem pair of PDZ domains) with GPER1 (via C-terminus tail motif); the interaction is direct and induces the increase of GPER1 protein levels residing at the plasma membrane surface in a estradiol-independent manner. Interacts (via N-terminus tandem pair of PDZ domains) with NOS1 (via N-terminus domain). Interacts with SHANK3.

Subcellular location: Cell membrane; Peripheral membrane protein. Cell junction › synapse › postsynaptic cell membrane › postsynaptic density. Cell junction › synapse.
