Research Progress in the Linker of Fusion Protein

Fusion protein was a genetic expression product, which was composed by two or more head-to-tail ligation genic coding region that were controlled by the same regulatory sequence. The design of linker played an important part in the fusion protein with connecting peptide. Linker designing, linker construction, linker classify, the function of linker, the problem arised and solved in the fusion protein with linker, were reviewed in this article.
