Comparison of nucleotide and deduced amino acid sequences of coelacanth vasotocin and mesotocin genes. Conserved nucleotides are indicated by an asterisk and identical amino acid residues are shown in bold font. Sequential Arg residues, N-glycosylation sites and Leu-rich core segment in the vasotocin precursor are boxed. The sequential Arg residues serve as a processing signal between the neurophysin and copeptin. Intronic sequences are shown in lower case.
