  • Defects in stargazin affect AMPA-receptor trafficking.
  • Studies in the thalamus and cerebellum highlight specific functional deficits.

Conclusions:

  • The stargazer mouse model provides insights into absence seizures and ataxia.
  • Stargazin's role in synaptic plasticity is crucial.
  • Allelic series, including waggler and stargazer 3Jackson, are essential for dissecting stargazin function.
