General Information

Term

postsynaptic specialization

ID (Ontology)

GO:0099572 (Gene Ontology)

Definition

A network of proteins within and adjacent to the postsynaptic membrane. 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:22046028 ]
