postsynaptic density protein 95 is 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. This gene encodes a member of the membrane-associated guanylate kinase (MAGUK) family. It heteromultimerizes with DLG2. With DLG2 it is recruited into the same NMDA receptor and potassium channel clusters. These two MAGUK proteins may interact at postsynaptic sites to form a multimeric scaffold for the clustering of receptors, ion channels, and associated signaling proteins.
