Abstract [en]

We recently discovered a novel family of neuroactive peptides in nemerteans, which we have named alpha-nemertides (1). One of these peptides, nemertide alpha-1, has been the subject of detailed studies with regard to structure and effects. The peptide exhibits exceptional potency against a number of arthropod species. Moreover, in vitro experiments suggest that alpha-1 acts primarily on voltage-gated sodium channels, and that this action is selective for arthropods by two orders of magnitude over vertebrate species. Using transcriptomic and proteomic approaches, we have identified 10 alpha-nemertides, but this number is likely to increase. These peptides alongside with a series of mutants are currently under evaluation by our group, with the goal to improve our understanding of structure-function relationships. In addition, we are considering potential practical uses of alpha-nemertides. In this talk, I will describe the current status of this research project.
