  • 功能：
    Regulates the trafficking and gating properties of AMPA-selective glutamate receptors (AMPARs). Promotes their targeting to the cell membrane and synapses and modulates their gating properties by slowing their rates of activation, deactivation and desensitization. Does not show subunit-specific AMPA receptor regulation and regulates all AMPAR subunits. Thought to stabilize the calcium channel in an inactivated (closed) state.
  • 基因功能参考文献：
    1. The results from the current study demonstrate that there is an aberrant tissue expression of GABAAR alpha1 and beta2 subunits in the thalamus of PN7-9 juvenile stargazer mice, but that this early change equilibrates during later developmental stages (PN10-12 and PN13-15). PMID: 29099440
    2. Critically, by altering the two interacting loops of TARP gamma2 and TARP gamma8, the s could entirely remove all allosteric modulation of GluA2, without affecting formation of AMPA receptor-TARP complexes. PMID: 28871958
    3. Learning to cope with stress modulates anterior cingulate cortex stargazin expression in mice. PMID: 27003116
    4. show that upon release of glutamate, synaptic AMPARs were desensitized by transmitter by >90%. As glutamate levels subsequently fell, recovery of transmission occurred due to the presence of the AMPAR accessory protein stargazin that enhances the AMPAR response to low levels of transmitter. PMID: 28919175
    5. we show that the TARP gamma-2 (stargazin) is present in spinal dorasl horn neurons and is necessary in a form of inflammatory pain-induced plasticity PMID: 28559374
    6. the density of AMPARs correlates with that of TARP gamma-2 across SCC synapses and its high expression is linked to high-density AMPAR expression at perforated type of pyramidal cell synapses PMID: 27076426
    7. in the absence of stargazin, the refinement of the retinogeniculate synapse is specifically disrupted during the experience-dependent phase. Stargazin expression and phosphorylation increased with visual deprivation. PMID: 24882000

    9. Thus, gamma-7 is capable of supporting a component of excitatory transmission in PCs, sufficient to maintain essentially normal motor behavior, in the absence of gamma-2. PMID: 25583485

    15. the loss of gamma-2 in stargazer mouse stellate cells induces changes in synaptic transmission that cannot be compensated for by the remaining TARP gamma-7. PMID: 22581185
    16. Results indicate that hippocampal and cerebellar long-term depression share a common pathway, namely dephosphorylation of stargazin by calcineurin. PMID: 22239345
    17. Ataxic phenotype in stargazers is primarily due to absence of AMPA receptors at cerebellar mossy-fiber-granule cell synapses. PMID: 22055455

    20. Results suggest that TARPs gamma-2 and gamma-7 cooperatively promote synaptic expression of cerebellar AMPA receptors, and the latter also promotes glial expression. PMID: 20529126
    21. Stargazin counteracts the Gbetagamma-induced inhibition of Ca(V)2.2 channel currents, caused either by coexpression of the Gbetagamma dimer or by activation of a G protein-coupled receptor. PMID: 20435886

    26. Stargazin plays a role in AMPA receptor trafficking through the early compartments of the biosynthetic pathway. PMID: 15689545

    32. Cacng2 subunit expression alters the voltage dependence of channel activity and reduces N-type calcium channel synthesis via activation of the endoplasmic reticulum unfolded protein response. PMID: 17376992
    33. This study indicates that TARPs, in particular gamma-2, are essential for early development, and that most neurons express multiple members of this functionally redundant protein family. PMID: 18634809
    34. Results show that neuronal AMPA receptors and recombinant AMPA receptors coexpressed with stargazin autoinactivate at high concentrations of glutamate, whereas recombinant AMPA receptors expressed alone do not. PMID: 19146816
