Characterisation of Bombyx mori Odorant-binding Proteins Reveals that a General Odorant-binding Protein Discriminates Between Sex Pheromone Components [PDF]
Journal of Molecular Biology, 2009 In many insect species, odorant-binding proteins (OBPs) are thought to be responsible for the transport of pheromones and other semiochemicals across the sensillum lymph to the olfactory receptors (ORs) within the antennal sensilla.

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.

Odorant binding initially occurring at the central pocket in bovine odorant-binding protein [PDF]
Biochemical and Biophysical Research Communications, 2005 Why bovine odorant-binding protein (OBPb), among OBP family, assumes a dimeric structure has been unclear. Here we clarified, by measuring the fluorescence of intrinsic tryptophan and tyrosine residues of intact OBPb and OBPb whose C-terminal 10 amino acids were deleted, that odorant enters the central pocket formed by the dimerization when OBPb first ...

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 ...

Critical Reviews in Biochemistry and Molecular Biology, 1994
Odorant-binding proteins (OBPs) are low-molecular-weight soluble proteins highly concentrated in the nasal mucus of vertebrates and in the sensillar lymph of insects. Their affinity toward odors and pheromones suggests a role in olfactory perception, but their physiological function has not been clearly defined.

Immunocytochemistry of Odorant-Binding Proteins
1994Odorant-binding proteins are small water-soluble proteins that have been detected in the perireceptor compartment of olfactory receptor cells of vertebrates and insects [1,2]. Although their definite physiological role in olfaction is still unclear, similar functions have been proposed in stimulus transport or inactivation [1–6].
