An Efficient Genome-Wide Fusion Partner Screening System for Secretion of Recombinant Proteins in Yeast.
Rarely issued to produce recombinant proteins in the yeast Saccharomyces cerevisiae, we developed a new filtration system optimal genome-wide translational fusion partner (TFP), which involves the secretion signal optimal recruitment and fusion partner. A TFP library constructed from genomic and Multi-species Recombinant Proteins cDNA libraries were cut using a technique based invertase signal sequence trap. The efficiency of the system was demonstrated using two rarely secreted protein, human interleukin (HIL) -2 and Hil-32. TFPs optimal for the secretion-2 and Hil Hil-32 very easily, resulting in secretion of this protein to hundreds mg / L. In addition, many expressed yeast secretion signal and fusion partners are identified, leading to the efficient secretion of recombinant proteins. TFPs been found to be useful for a hypersecretion of other recombinant proteins in yields of up to several g / L. This screening technique could provide a new method for the production of various typ
