Expression VectorNApLS4 (derived from mYSK)
Assay MethodsWestern botWestern blot
ResultsModerate expression>5 fold increase in synthesis rate and 50-fold increase in the steady state level of protein.
Protein FunctionAntibody
Recoding PurposeTo improve expression
Synthesized ByAuthors
Recoding Method115 of 215 codons were replaced with yeast-preferred codons defined in Ikemura 1982. Only the
optimal codons (most frequently used) were used for each amino acid.

Publication TitleEvaluation of foreign gene codon optimization in yeast: expression of a mouse IG kappa chain
AbstractWe have optimized the codons in an immunoglobulin kappa chain gene to those preferred in the yeast Saccharomyces cerevisiae. The mutant and wild type kappa chain genes were each fused with a synthetic invertase signal peptide that also contained only yeast-preferred codons, and expressed in the F762 yeast strain. The use of yeast-preferred codons resulted in a more than 5-fold increase in the rate of synthesis and at least a 50-fold increase in the steady state level of protein.

SummaryThe mouse IG kappa chain gene was codon optimized for expression in S. cerevisiae. A full optimization method was used and the protein was successfully over-expressed.
