Evolutionary mechanisms of conotoxins have been investigated in several superfamilies, but there is no phylogenetic analysis on M-superfamily conotoxins. In this study, we characterized identical sequences, gene structure, novel cysteine frameworks, functions and evolutionary mechanisms of M-superfamily conotoxins. Identical M-superfamily conotoxins can be found in different Conus species from the analysis of novel 467 M-superfamily conotoxin sequences and other published M-superfamily conotoxins sequences. M-superfamily conotoxin genes consist of two introns and three exons from the results of genome walking. Eighteen cysteine frameworks were identified from the M-superfamily conotoxins, and 10 of the 18 may be generated from framework III. An analysis between diet types and phylogeny of the M-superfamily conotoxins indicate that M-superfamily conotoxins might not evolve in a concerted manner but were subject to birth-and-death evolution. Codon usage analysis shows that position-specific codon conservation is not restricted to cysteines, but also to other conserved residues. By analysing primary structures and physiological functions of M-superfamily conotoxins, we proposed a hypothesis that insertions and deletions, especially insertions in the third cysteine loop, are involved in the creation of new functions and structures of the M-superfamily conotoxins."xsd:string
