Gαqf04219/+ mutant larvae show a small decrease in spontaneous miniature neurotransmission. A compensatory increase in quantal content means that evoked neurotransmission is unaffected.
Gα49Bf04219 homozygotes die at around 10-12 hours post-hatching.
Gαqf04219/Galphaq[+], GluRIIASP16 has abnormal neurophysiology phenotype
One copy of Gαqf04219 partially prevents the compensatory increase in quantal content seen in the NMJs of GluRIIASP16 mutant larvae with reduced quantal size, resulting in impaired evoked neurotransmission. These is some increase in quantal content compared with Gαqf04219/+ controls, but not enough to compensate for the reduced quantal size.
