Fig. 2.

Ctenidin 1 and 2 cDNA sequences. The deduced amino acid sequence is presented under the nucleotide sequence. The mature peptide sequence is underlined; the part missing in ctenidin 2 is double underlined. The nucleotide sequence of the mature peptide is in bold. The dotted line marks the post-translationally cleaved off lysine and the glycine residue involved in C-terminal amidation of the other glycine. Asterisks mark the stop codon. The polyadenylation signal is shown in bold italics
