Expression cassettes of IL-22. SP, signal peptide of apf gene (including its start codon); RBS, ribosomal binding site; P, apf promoter; C-ter, C-terminal part of apf gene; mouse IL-22 or prtP translational stop codon (both indicated with an arrowhead) and the transcription terminator of apf gene (indicated with a lollipop). The C-terminal part of the apf gene is not translated
