The postsynaptic density
The postsynaptic density (PSD) is a protein dense specialization attached to the postsynaptic membrane. PSDs were originally identified by electron microscopy as an electron-dense region at the membrane of a postsynaptic neuron. The PSD is in close apposition to the presynaptic active zone and ensures that … Visa mer The structure and composition of the PSD have been the focus of numerous molecular studies of synaptic plasticity, a cellular model of learning and memory. PSDs are sized on the order of 250 to 500 nanometres in … Visa mer The PSD has been proposed to concentrate and organize neurotransmitter receptors in the synaptic cleft. The PSD also … Visa mer • Postsynaptic Density- Cell Centered Database Visa mer Webb26 jan. 2024 · Postsynaptic densities are nanodomains comprised of about 1000 unique proteins that interact with one another via specialized multipotent scaffolding molecules. 1 Postsynaptic density (PSD-95) is the most abundant scaffolding protein within the postsynaptic density. 2–4 PSD-95 links glutamate receptors, signaling molecules, and …
