Or22b

Gene
Or22b
Protein
Odorant receptor 22b
Organism
Drosophila melanogaster
Length
397 amino acids
Function
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. Involved in the behavioral responses to esters. Complexes with Orco to form odorant-sensing units, providing sensitive and prolonged odorant signaling and calcium permeability. They are necessary and sufficient to promote functional reconstitution of odor-evoked signaling in sensory neurons that normally respond only to carbon dioxide.
Similarity
Belongs to the insect chemoreceptor superfamily. Heteromeric odorant receptor channel (TC 1.A.69) family. Or2a subfamily.
