Large-scale identification of odorant-binding proteins and chemosensory proteins from expressed sequence tags in insects

摘要

BackgroundInsect odorant binding proteins (OBPs) and chemosensory proteins (CSPs) play an important role in chemical communication of insects. Gene discovery of these proteins is a time-consuming task. In recent years, expressed sequence tags (ESTs) of many insect species have accumulated, thus providing a useful resource for gene discovery.
