General Information
Term postsynaptic density ID (Ontology) GO:0014069 (Gene Ontology)
Definition An electron dense network of proteins within and adjacent to the postsynaptic membrane of an asymmetric, neuron-neuron synapse. Its major components include neurotransmitter receptors and the proteins that spatially and functionally organize them such as anchoring and scaffolding molecules, signaling enzymes and cytoskeletal components.[ PubMed:14532281 ]
Also Known As "neuronal postsynaptic density" ; "post synaptic density" ; "post-synaptic density"
