Functional Evaluation of the Signal Peptides of Secreted Proteins

Abstract

Here, we describe a method that can be used to evaluate the function of predicted signal peptides. This method utilizes the yeast Saccharomyces cerevisiae YTK12 strain and pSUC2 vector in which the pSUC2 vector with fused predicted signal peptide is transformed into yeast. The function of the signal peptides can be evaluated by using different selective media and color reaction. In this protocol, we provide the detailed description of manipulation in order to implement easily.
