SynapticProteinsattheSynapticJunction
The postsynaptic density (PSD) is a submembranous structure at the postsynaptic membrane mainly at the excitatory synapses. The neurotransmitter receptors are assembled and fixed at the PSD, and several molecules implicated in the synaptic plasticity are also enriched. PSD-95/synapse-associated protein (SAP) 90 is involved in the molecular organization of these components of the PSD and essential for learning and mem......阅读全文
