ConoServer is a database specializing in the sequence and structures of conopeptides, which are peptides expressed by carnivorous marine cone snails. A fascinating feature of these peptides is their high specificity and affinity towards human ion channels, receptors and transporters of the nervous system. This makes conopeptides an interesting resource for the physiological studies of neuroreceptors and promising drug leads. Conopeptides are further described here and a selection of recent reviews on the subject can be found
