Abstract excerpt
Conopeptides display prominent features of hypervariability and high selectivity of large gene families that mediate interactions between organisms. Remarkable sequence diversity of O-superfamily conotoxins was found in a worm-hunting cone snail Conus miles. Five novel cDNA sequences encoding O-superfamily precursor peptides were identified in C. miles native to Hainan by RT-PCR and 3'-RACE. They share the common...
