Summary: Voltage-dependent calcium channels couple membrane depolarization in a number of cellular processes. These activities are regulated by distinct channels composed of the pore-forming alpha-1 subunit and the modulatory beta, alpha-2/delta and gamma subunits. The protein encoded by this gene represents one of the gamma subunits. It is an integral membrane protein that is thought to stabilize the calcium channel in an inactive (closed) state. This gene is located in a cluster with two similar gamma subunit-encoding genes on chromosome 1. The mRNA for this gene is believed to initiate translation from a non-AUG (CUG) start codon.

Mechanisms underlying TARP modulation of the GluA1/2-gamma8 AMPA receptor.
Title: Mechanisms underlying TARP modulation of the GluA1/2-γ8 AMPA receptor.
this study presents a cryo-electron microscopy structure of the heteromeric GluA1/2 receptor associated with two transmembrane AMPAR regulatory protein (TARP) gamma8 auxiliary subunits, the principal AMPAR complex at hippocampal synapses.
Title: Architecture of the heteromeric GluA1/2 AMPA receptor in complex with the auxiliary subunit TARP γ8.
AMPA-induced currents were recorded in the neurons using a whole-cell recording method. RESULTS: Four-hour exposure to AMPA significantly decreased the protein levels of TARP gamma-8 and GluA1 in the neurons at 17-18 DIV, but did not change the protein level of TARP gamma-8 in the neurons cultured at 7-8 DIV.
Title: Activity- and development-dependent down-regulation of TARPγ8 and GluA1 in cultured rat hippocampal neurons.
TARP gamma-8 has an important role in the trafficking and function of the AMPA receptor complex.
Title: TARP γ-8 glycosylation regulates the surface expression of AMPA receptors.
the gamma-8 P/A-rich region is essential for binding calcineurin, suggesting that the gamma-8/calcineurin complex may regulate AMPA receptor phosphorylation and trafficking
Title: Direct association of the unique C-terminal tail of transmembrane AMPA receptor regulatory protein γ-8 with calcineurin.

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.
