Or74a

Gene
Or74a
Protein
Odorant receptor 74a
Organism
Drosophila melanogaster
Length
404 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. May form a complex with Orco to form odorant-sensing units, providing sensitive and prolonged odorant signaling and calcium permeability. Involved in the behavioral responses to octanol, anisole, and 2-heptanone.
Similarity
Belongs to the insect chemoreceptor superfamily. Heteromeric odorant receptor channel (TC 1.A.69) family. Or1a subfamily.
