Summary: Predicted to enable ionotropic olfactory receptor activity and odorant binding activity. Involved in detection of chemical stimulus involved in sensory perception of smell. Predicted to be located in dendrite membrane. Predicted to be active in plasma membrane. Is expressed in embryonic/larval antennal lobe; larval antennal lobe glomerulus 59a; larval olfactory receptor neuron Or59a; olfactory receptor neuron of dorsal organ; and third segment of antenna.
