CC -!- FUNCTION: Odorant receptor which mediates acceptance or avoidance
CC behavior, depending on its substrates. The odorant receptor repertoire
CC encodes a large collection of odor stimuli that vary widely in
CC identity, intensity, and duration. May form a complex with Orco to form
CC odorant-sensing units, providing sensitive and prolonged odorant
CC signaling and calcium permeability. Involved in the behavioral
CC responses to ethyl acetate and pentyl acetate.
CC {ECO:0000269|PubMed:21613503, ECO:0000269|PubMed:21857978}.
CC -!- SUBUNIT: Interacts with Orco. Complexes exist early in the endomembrane
CC system in olfactory sensory neurons (OSNs), coupling these complexes to
CC the conserved ciliary trafficking pathway (By similarity).
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Multi-pass membrane
CC protein {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Expressed in olfactory sensory neurons in the
CC antenna. {ECO:0000269|PubMed:10943836}.
CC -!- MISCELLANEOUS: The atypical heteromeric and topological design of the
CC odorant receptors appears to be an insect-specific solution for odor
CC recognition, making the OR/Orco complex an attractive target for the
CC development of highly selective insect repellents to disrupt olfactory-
CC mediated host-seeking behaviors of insect disease vectors. Odor-evoked
CC OR currents are independent of known G-protein-coupled second messenger
CC pathways.
CC -!- SIMILARITY: Belongs to the insect chemoreceptor superfamily.
CC Heteromeric odorant receptor channel (TC 1.A.69) family. Or2a
CC subfamily. {ECO:0000305}.
