MPDZ interacts with HTR2C (serotonin receptor 2C) and provokes its clustering at the cell surface. Member of the NMDAR signaling complex and may play a role in control of AMPAR potentiation and synaptic plasticity in excitatory synapses. Highly enriched in postsynaptic densities (PSD). Localized to punctae on dendrites of hippocampal neurons and colocalizes with the synaptic marker PSD-95. Localized mainly in the Schmidt-Lanterman incisures of myelinating Schwann cells. In the retina, localizes to the sub-apical region adjacent to the adherens junction complex at the outer limiting membrane. Enriched at the tight junctions of epithelial cells. Association to the tight junctions depends on CXADR. Contains 13 PDZ domains. Three alternatively spliced isoforms have been described. Note: This description may include information from UniProtKB.
