Casein Kinase 2 Regulates the NR2 Subunit Composition of Synaptic NMDA Receptors
N-methyl-D-aspartate (NMDA) receptors (NMDARs) play a central role in development, synaptic plasticity, and neurological disease. NMDAR subunit composition defines their biophysical properties and downstream signaling. Casein kinase 2 (CK2) phosphorylates the NR2B subunit within its PDZ-binding domain; however, the consequences for NMDAR localization and function are unclear. Here we show that ...
متن کاملActivated CaMKII couples GluN2B and casein kinase 2 to control synaptic NMDA receptors.
Synaptic activity triggers a profound reorganization of the molecular composition of excitatory synapses. For example, NMDA receptors are removed from synapses in an activity- and calcium-dependent manner, via casein kinase 2 (CK2) phosphorylation of the PDZ ligand of the GluN2B subunit (S1480). However, how synaptic activity drives this process remains unclear because CK2 is a constitutively a...
متن کاملThe Effects of NR2 Subunit-Dependent NMDA Receptor Kinetics on Synaptic Transmission and CaMKII Activation
N-Methyl-D-aspartic acid (NMDA) receptors are widely expressed in the brain and are critical for many forms of synaptic plasticity. Subtypes of the NMDA receptor NR2 subunit are differentially expressed during development; in the forebrain, the NR2B receptor is dominant early in development, and later both NR2A and NR2B are expressed. In heterologous expression systems, NR2A-containing receptor...
متن کاملN-Terminal Domains in the NR2 Subunit Control Desensitization of NMDA Receptors
Recent molecular studies of glutamate channels have provided increasingly detailed models of the agonist-binding site and of the channel pore. However, little information is available on the domains involved in channel gating. We examined the molecular determinants for the NR2-subunit specificity of glycine-independent desensitization of NMDA channels using NR2C/NR2A chimeric subunits expressed...
متن کاملPresynaptic control of subunit composition of NMDA receptors mediating synaptic plasticity.
Subunit composition of subsynaptic transmitter receptors is controlled presynaptically in the developing neuromuscular junction. To investigate presynaptic regulation of NMDA receptor subunit composition in the CNS, we co-cultured different types of hippocampal explants with dissociated target neurons. Postsynaptic NMDA receptors were studied using whole-cell patch-clamp recordings. After 1 wee...
