AMPA receptor auxiliary subunit TARP gamma-8, via its PDZ-binding motif, is indispensable for both basal synaptic transmission and Long-term potentiation.
Title: LTP requires postsynaptic PDZ-domain interactions with glutamate receptor/auxiliary protein complexes.

Title: Control of AMPA receptor activity by the extracellular loops of auxiliary proteins.
these findings demonstrate that TARPgamma-8 is a crucial mediator of CaMKII-dependent Long Term Potentiation and therefore a molecular target that controls synaptic plasticity and associated cognitive functions.
Title: CaMKII Phosphorylation of TARPγ-8 Is a Mediator of LTP and Learning and Memory.
TARP gamma-8 is the only TARP expressed at nonperforated type of pyramidal cell synapses, playing an essential role in low-density or basal AMPAR expression
Title: TARP γ-2 and γ-8 Differentially Control AMPAR Density Across Schaffer Collateral/Commissural Synapses in the Hippocampal CA1 Area.
This study demonstrated that genetic inactivation of this specific population of AMPA receptors results in modest changes in behavior characterized by a mild hyperactivity.

coexpression of both auxiliary subunits,CKAMP44 and TARP gamma-8 is necessary for the efficient targeting of AMPARs to the cell surface of dentate gyrus granule cells
Title: Coexpressed auxiliary subunits exhibit distinct modulatory profiles on AMPA receptor function.
The results of thia study suggested that there are distinct TARP-dependent mechanisms for synaptic transmission and long term potential.
Title: PDZ binding of TARPγ-8 controls synaptic transmission but not synaptic plasticity.
Tarp gamma-8 (and CNIH-2) functionally interact with common AMPA receptor complexes in hippocampus; however, TARP gamma-8-containing hippocampal neurons do not display resensitization.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
