Expression VectorJM101(pNIL2-22)JM101(pNIL2-22)
Assay MethodsSDS-PAGE and ImmunoblotSDS-PAGE and Immunoblot
ResultsThe wild type gene yielded very little immunoreactive IL-2 when grown in E. coli.The recoded IL-2 gene resulted in expression up to 16 times as much as the natural gene.
Protein FunctionMediates immune response by acting as growth factor for T cells
Recoding PurposeTo improve expression
Synthesized ByAuthors
Recoding MethodThe recoding method included comparing amino acid codons found in the human IL-2 cDNA to codons
found in highly expressed E. coli genes. The codons were recoded to increase highly used codons in
E. coli from 43% to 85% of the total gene.

Publication TitleDesign, synthesis and expression of a human interleukin-2 gene incorporating the codon usage bias found in highly expressed Escherichia coli genes
AbstractA synthetic gene encoding human interleukin-2 (IL-2) was designed such that the codon usage bias resembled that found in highly expressed Escherichia coli genes. The percentage of preferred codons was increased from 43% in the native cDNA sequence to 85% in the synthetic sequence. The cDNA and synthetic IL-2 genes were placed under the control of the trc promoter and expressed in E. coli JM101. While Northern blot analysis of IL-2 mRNA from each genetic construct demonstrated equivalent message half-lives, immunoblot and bioactivity analyses showed the synthetic gene to direct the synthesis of up to 16 times more IL-2 than the native cDNA sequence.

SummaryThe goal of this experiment was to increase production of human interleukin-2 protein in E. coli. The wild-type gene was recoded (method of recoding was not explained) and expressed in JM101 strain E. coli. The recoded gene showed an increase in protein production of up to 16 times that of the wild type gene.
CommentsThe recoding method was not explained in the paper.
