The response of the ab1C olfactory receptor neuron to CO[[2]] is normal in mutant flies. The odour responses of the ab1A, ab2A and ab3A ORNs are normal in mutant flies.

Gγ1^NP1535 flies exhibit significantly lowered proboscis extension reflex rates in response to 100mM sucrose compared to controls. However, Gγ1^NP1535/Gγ1^ΔP transheterozygote flies show normal proboscis extension reflex rates. Gγ1^NP1535 flies show markedly lower gustatory receptor neuron responses to 10-100mM sucrose, 10-100mM fructose, 30mM glucose and 10 and 30mM trehalose. There is no significant reduction of nerve responses to water and salt.
