Plays a role in detection and sensitivity to pheromones and signal transduction of the fatty-acid-derived male pheromone 11-cis vaccenyl acetate (cVA). Acts in concert with Snmp and lush to capture cVA molecules on the surface of Or67d expressing olfactory dendrites and facilitate their transfer to the odorant-receptor Orco complex. Necessary to mediate behavioral responses to cVA by regulating both male and female mating behavior. Activation of Or67d neurons by cVA inhibits courtship of other males, whereas in females their activation promotes receptivity to other males. May form a complex with Orco to form odorant-sensing units, providing sensitive and prolonged odorant signaling and calcium permeability. Interacts with Orco. Complexes exist early in the endomembrane system in olfactory sensory neurons (OSNs), coupling these complexes to the conserved ciliary trafficking pathway (By similarity). Expressed in antenna. Mutant males inappropriately court other males, whereas mutant females are less receptive to courting males. The atypical heteromeric and topological design of the odorant receptors appears to be an insect-specific solution for odor recognition, making the OR/Orco complex an attractive target for the development of highly selective insect repellents to disrupt olfactory-mediated host-seeking behaviors of insect disease vectors. Odor-evoked OR currents are independent of known G-protein-coupled second messenger pathways. Belongs to the insect chemoreceptor superfamily. Heteromeric odorant receptor channel (TC 1.A.69) family. Or67d subfamily.
