DESCRIPTION
Also known as OR19A_DROME, Or19a. Odorant receptor which mediates acceptance or avoidance behavior, depending on its substrates. The odorant receptor repertoire encodes a large collection of odor stimuli that vary widely in identity, intensity, and duration. May form a complex with Orco to form odorant-sensing units, providing sensitive and prolonged odorant signaling and calcium permeability. Involved in the preference for citrus fruits for oviposition, especially through the response to valencene, the primary ligand of Or19a. Larvae growing on citrus fruits suffer a reduced risk of parasitism since endoparasitoid wasps that parasitize larvae are strongly repelled by the smell of citrus, as well as by valencene. 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).
