Background:

  • Cone snails (genus Conus) are the largest genus of marine animals, with over 500 species.
  • All species are venomous, utilizing complex peptide mixtures for predation and other functions.

Purpose of the Study:

  • To explore the diversity and pharmacological potential of Conus peptides.
  • To highlight their applications in neuroscience research and drug development.

Main Methods:

  • The study reviews existing literature on Conus peptide diversity, structure, and function.
  • Mechanisms contributing to peptide diversity, including gene structure and post-translational modifications, are discussed.

Main Results:

  • Over 50,000 distinct Conus peptides are estimated, each targeting specific ion channels, receptors, or transporters.
