| 英文摘要 | Using in vitro selection method to isolate nucleic acids, peptides and proteins has been studied intensively in recent years. In vitro mRNA display is a new and effective technique for peptides selection, and the rationale of this technique is that a synthetic mRNA with puromycin could covalently link with the protein that it encodes, thus an mRNA-protein fusion is formed. This approach has been used in identification of many functional peptides. The peptides binding with thymidylate synthase RNA were isolated using mRNA display technique from a large peptide library (>10(13) different sequences). The selection scheme was constructed, and the experimental conditions, including library synthesis, formation of RNA-peptide fusion and RNA immobilization were optimized. Eight cycles have been processed and the results confirmed that the selected peptides could bind with thymidylate synthase mRNA specifically. Compared the amino acid sequences of the selected peptides with those from the initial random library, the basic and aromatic residues in selected peptides were enriched significantly, suggesting these peptide regions may be important in the peptide-TS mRNA interaction. As a novel in vitro selection approach, mRNA display technique would be developed as a powerful tool for isolation of functional peptides and proteins that could interact with immobilized targets with high affinity and specificity.; Using in vitro selection method to isolate nucleic acids, peptides and proteins has been studied intensively in recent years.
