Protein: Multiple PDZ domain protein (Multi-PDZ domain protein 1) (O55164)
Organism: Rattus norvegicus (Rat)
Function: Member of the NMDAR signaling complex that may play a role in control of AMPAR potentiation and synaptic plasticity in excitatory synapses. Promotes clustering of HT2RC at the cell surface.
Subcellular location: Endomembrane system. Cell junction, tight junction. Synapse. Apical cell membrane {ECO:0000269|PubMed:11150294}. Postsynaptic density. Cell projection, dendrite. Synapse, synaptosome. Note=Associated with membranes. Enriched at the tight junctions of epithelial cells. Association to the tight junctions depends on CXADR. In the retina, localizes to the sub-apical region adjacent to the adherens junction complex at the outer limiting membrane (By similarity). Colocalizes with HTR2C on the apical membrane of epithelial choroid plexus cells (PubMed:11150294). Localized mainly in the Schmidt-Lanterman incisures of myelinating Schwann cells. Highly enriched in postsynaptic densities (PSD). Localized to punctae on dendrites of hippocampal neurons and colocalizes with the synaptic marker DLG4. {ECO:0000250, ECO:0000269|PubMed:11150294}.
