Also found in: Wikipedia.

o·dor·ant bind·ing pro·tein

proteins in nasal mucus that bind lipophilic odor-producing molecules and transfer them to the olfactory receptors. Similar proteins may mediate taste.

A comparative study of odorant binding protein genes: differential expression of the PBP1-GOBP2 gene cluster in Manduca sexta (Lepidoptera) and the organization of OBP genes in Drosophila melanogaster (Diptera).
The odorant binding proteins (OBPs) are the first molecular filters favoring insects' sensitivity because they act in odor selection [11-13].
Li et al., [7] pointed out that Odorant binding proteins (OBPs) and chemosensory proteins (CSPs) are two of the best known olfactory proteins in insects, but chemosensory protein (CSPs) is the only carrier transmits of recognition signals to the olfactory receptor neurons.
