The yeast protein expression system is a highly cost-effective eukaryotic expression system capable of both secretory and intracellular expression.

Yeast systems possess post-translational processing capabilities; the expressed foreign proteins undergo folding and glycosylation, resulting in greater stability compared to proteins produced in prokaryotic systems. This makes them particularly suitable for eukaryotic gene expression and the production of functional proteins.

Yeast secretory expression allows the target protein to be released into the extracellular medium, facilitating the recovery of high-purity protein.

The numerous advantages of yeast expression systems have led to their increasingly widespread research and application.

No self-produced endotoxins;

The product can be post-translationally modified: glycosylation, phosphorylation, acyl esterification, etc., and the protein is more likely to be biologically active;

The product can be folded correctly and secreted efficiently;

It is more stable than proteins expressed in prokaryotic cells and is particularly suitable for expressing and preparing functional proteins: such as tuberculosis proteins, defensin proteins, interleukin proteins, and cytokines.
