Expression of a complete GluRIIA cDNA is governed by the Mhc promoter.
wild-type
GluRIIAMhc.PP rescues Df(2L)AD1
GluRIIAMhc.PP rescues Df(2L)SP22
GluRIIAMhc.PP rescues GluRIIASP16
Rescues the lethality of Df(2L)SP22 or Df(2L)AD1.
Decrease in quantal size and increase in quantal content of GluRIIA mutants is rescued by GluRIIAMhc.PP.
