The postsynaptic density
Did you know?
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 WebbThe postsynaptic density (PSD) is a large macromolecular machine that lines the postsynaptic membrane at glutamatergic synapses. The PSD is responsible for synaptic transmission, signal transduction, and processing and provides a …
WebbProSAPs/Shanks build large homo- and heteromeric protein complexes at excitatory synapses and organize the complex protein machinery of the postsynaptic density in a laminar fashion. Here we demonstrate that genetic deletion of ProSAP1/Shank2 results in an early, brain-region-specific upregulation of ionotropic glutamate receptors at the … Webb4 apr. 2024 · Here, we utilize a postsynaptic density minimal system to demonstrate that biochemical reconstitution can be applied on supported lipid bilayer (SLB); we have also incorporated actin cytoskeleton ...
