Chemosensory Proteins: A Versatile Binding Family

Chemosensory Proteins (CSPs), a family of small soluble polypeptides, own their name to their highly abundant expression in chemosensory organs of insects. However, CSPs are extremely versatile and perform different tasks in chemical communication, but also in unrelated functions, such as development and insecticide resistance. Their multifunction is certainly linked to their simple structure and easy refolding.
