Odorant‐binding proteins of mammals
Biological Reviews, 2021ABSTRACTOdorant‐binding proteins (OBPs) of vertebrates belong to the lipocalin superfamily and perform a dual function: solubilizing and ferrying volatile pheromones to the olfactory receptors, and complexing the same molecules in specialized glands and assisting their release into the environment.

Odorant-binding proteins of the mouse
Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1995After the isolation of two odorant-binding proteins (OBP-I and OBP-II) from mouse nasal tissue, we have purified two additional OBPs, which bind tritiated 2-isobutyl-3-methoxypyrazine. OBP-III is a homodimer with subunits of M(r) 22,000 and pI 4.2. OBP-IV is a homodimer with subunits of M(r) 21,000 and pI 4.85.

Odorant-binding proteins in insects
Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1995This paper reviews the characteristics of pheromone and odorant-binding proteins (OBP) in insects, with particular reference to Lepidoptera. They are small (15 kDa) soluble proteins, very concentrated in the lymph of chemosensory sensilla and belonging to two major classes, pheromone-binding proteins (PBP) and general odorant-binding proteins.

Enhancement of odorant detection sensitivity by the expression of odorant-binding protein
Biosensors and Bioelectronics, 2008Odorant-binding proteins are low molecular weight, soluble proteins that are secreted by glands of the nasal cavity. Their function is known to be the transport of hydrophobic odorants. This feature is important to artificial olfactory biosensors, which operate in the aqueous phase. In this study, one of rat odorant-binding proteins, OBP3, was inserted

Binding of selected odorants to bovine and porcine odorant-binding proteins
Chemical Senses, 1993Twenty floral smelling tetrahydropyranyl and tetrahydrofuranyl ethers, and 12 additional compounds with different odours were used in ligand-binding experiments with purified 19 kDa bovine OBP and 22 kDa porcine OBP. Most of the odorants examined were found to be good ligands for both proteins, with dissociation constants in the micromolar range; the ...

Mammalian odorant binding proteins
Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 2000Odorant binding proteins (OBPs) pertain to one of the most abundant classes of proteins found in the olfactory apparatus. OBPs are a sub-class of lipocalins, defined by their property of reversibly binding volatile chemicals, that we call 'odorants'. Numerous sequences of OBPs are now available, derived from protein sequencing from nasal mucus material,

The Liriomyza trifolii is a highly invasive polyphagia pest. Understanding the physiological functions of odorant binding proteins (OBPs) in the chemical communication of L. trifolii can lead to effective pest management strategies. Seven full-length OBPs were identified by transcriptome screening of L. trifolii adults.

DyBOBS: A Dynamic Biomimetic Assay for Odorant-Binding to Odor-Binding Protein
Chemosensory Perception, 2010An in vitro system was developed to mimic the structural and flow conditions of the human olfactory epithelium and to measure the dynamics of odorant-binding to odor-binding protein (OBP). A hydrophilic fused silica capillary, coated internally with a thin (about 1.3 µm) aqueous film of recombinant rat-OBP3 mimicked the human olfactory epithelium ...
