Functional Evolution of Odorant Binding Proteins Genes in Drosophila melanogaster
… chemosensory ability through combinatorial odorant recognition in a functionally redundant system. Odorant binding proteins (OBPs) are the first components of the insect olfactory system to encounter odorants. Despite their abundant expression, little is known about their role in …

A Novel Role for Odorant Binding Proteins in Deactivation of Drosophila Olfactory Neurons
In insects, odorant binding proteins are a large and diverse group of low molecular weight proteins secreted into the fluid bathing olfactory and gustatory dendrites. The best-characterized OBP, known as LUSH, is required in Drosophila melanogaster for the detection of physiological levels of the …

Studies on Host-Seeking Behavior and Differential Chemosensory Gene Expression in Above- and Below-ground Culex Pipiens
… the expression of two chemosensory genes: odorant binding proteins (OBPs) 2 and 12. Both OBPs were more highly expressed in the heads of human-preferring females. While the patterns of OBP2 expression indicate that it may contribute to human host detection, OBP12 expression patterns are …

Chemosensory gene expression analysis in the argentine ant, linepithema humile
… of a subset of chemosensory genes, including odorant receptors (Ors) and odorant binding proteins (OBPs), in the invasive Argentine ant, Linepithema humile. Fragments of two Ors were identified from a whole ant EST project, which suggested their potential importance in Argentine ant ecology. …

Function and evolution of seminal fluid components in Drosophila
Drosophila melanogaster seminal fluid proteins (SFPs) secreted by the male reproductive tract are transferred to females during mating and induce profound female post-mating behavioral and physiological shifts. Many SFPs work in concert with female-derived molecules to promote fertility. However, …

Discovery and Phylogeny of the Odorant Binding and Chemosensory Proteins of Diabrotica Virgifera Virgifera (Coleoptera: Chrysomelidae) and Rhagoletis (Diptera: Tephritidae)
… and their evolution. Evidence suggests that both odorant-binding proteins (OBPs) and neuronal receptor proteins play roles in odorant recognition. One hypothesized function of chemosensory proteins (CSPs) and OBPs is to bind and transport specific odorants to olfactory receptors, thereby acting as …

Two Odorant-Binding Protein Genes in Mosquitoes: Comparative Genomics, Expression, and Function
Insect Odorant-Binding Proteins (OBPs) are small, water-soluble molecules that solubilize hydrophobic odorant molecules in the sensillum lymph and transport them to their cognate receptors in the olfactory receptor neurons. With the availability of the genome sequence of the African malaria …

COMPARATIVE GENOMICS OF CHEMOSENSORY GENE FAMILIES AMONG MEMBERS OF THE HELIOTHINAE
… curated two chemosensory gene families, the odorant receptors (ORs) and odorant binding proteins (OBPs), in C. virescens. In total, I identified 80 ORs, 1 Orco and 49 OBPs. Three types of OBPs were identified according to the number and positions of conserved cysteine residues: 34 classic …

Reproductive Genomics in the Stick Insect Clitarchus hookeri
… a wide variety of gene families, including odorant binding proteins (OBPs), chemosensory proteins, odorant receptors, ionotropic receptors and gustatory receptors. Among them, OBPs have three recently duplicated copies (OBP4, OBP5 and OBP6) that may underlie key adaptive events during …
