Figure 1. Schematic representation of the beta-defensin gene in Atlantic cod.

Pale yellow boxes represent partial 5′ and 3′untranslated regions. Red boxes indicate the coding region corresponding to the 66 amino acid residue peptide precursor. The predicted signal peptide and important secondary structure elements in the mature peptide are boxed. Conserved cysteine residues are highlighted in bold letters and predicted disulphide linkage patterns are also shown.
