Identification of PSD-95 Palmitoylating Enzymes
UNLABELLED Postsynaptic density (PSD)-95, the most abundant postsynaptic scaffolding protein, plays a pivotal role in synapse development and function. Continuous palmitoylation cycles on PSD-95 are essential for its synaptic clustering and regulation of AMPA receptor function. However, molecular mechanisms for palmitate cycling on PSD-95 remain incompletely understood, as PSD-95 depalmitoylati...
متن کاملMobile DHHC palmitoylating enzyme mediates activity-sensitive synaptic targeting of PSD-95
Protein palmitoylation is the most common posttranslational lipid modification; its reversibility mediates protein shuttling between intracellular compartments. A large family of DHHC (Asp-His-His-Cys) proteins has emerged as protein palmitoyl acyltransferases (PATs). However, mechanisms that regulate these PATs in a physiological context remain unknown. In this study, we efficiently monitored ...
متن کاملResults Psd-95 Shrna
To address the unsolved question of PSD-95 function I used short hairpin RNA (shRNA) to knock-down protein expression. shRNA mediated knock-down of protein expression is one of the established methods exploiting the naturally occurring expression control mechanism known as RNA interference (RNAi). Cells express shRNAs that are complementary to the mRNA they control. The shRNAs are processed and...

متن کاملDelineation of additional PSD-95 binding domains within NMDA receptor NR2 subunits reveals differences between NR2A/PSD-95 and NR2B/PSD-95 association.
N-methyl-D-aspartate (NMDA) receptors are clustered at synapses via their association with the PSD-95 (post-synaptic density-95) membrane associated guanylate kinase (MAGUK) family of scaffolding proteins. PSD-95 is the best characterized of this family. It is known to associate with NMDA receptor NR2 subunits via a conserved ES(E/D)V amino acid sequence located at their C-termini and thus to p...
