The genome of the silkmoth Bombyx mori contains 44 genes encoding odorant-binding proteins (OBPs) and 20 encoding chemosensory proteins (CSPs). In this work, we used a proteomic approach to investigate the expression of proteins of both classes in the antennae of adults and in the female pheromone glands. The most abundant proteins found in the antennae… (More)
Chemical communication in insects is mediated by soluble binding proteins, belonging to two large families, Odorant-binding Proteins (OBPs) and Chemosensory Proteins (CSPs). Recently, evidence has been provided that OBPs are involved in recognition of chemical stimuli. We therefore decided to investigate the expression of OBPs and CSPs in the honeybee at… (More)
We have purified an abundant lipocalin from the seminal fluid of the rabbit, which shows significant similarity with the sub-class of pheromone carriers "urinary" and "salivary" and presents an N-terminal sequence identical with that of an odorant-binding protein (rabOBP3) expressed in the nasal tissue of the same species. This protein is synthesised in the… (More)
Odorant-binding proteins (OBPs) and chemosensory proteins (CSPs) are small soluble polypeptides that bind semiochemicals in the lymph of insect chemosensilla. In the genome of Anopheles gambiae, 66 genes encode OBPs and 8 encode CSPs. Here we monitored their expression through classical proteomics (2D gel-MS analysis) and a shotgun approach. The latter… (More)
