Ligands selected from phage-displayed random peptide libraries tend to be directed to biologically relevant sites on the surface of the target protein. Consequently, peptides derived from library screenings often modulate the target protein's activity in vitro and in vivo and can be used as lead compounds in drug design and as alternatives to antibodies for target validation in both genomics an...
The display of peptide sequences on the surface of bacteria is a technology that offers exciting applications in biotechnology and medical research. Type 1 fimbriae are surface organelles of Escherichia coli which mediate D-mannose-sensitive binding to different host surfaces by virtue of the FimH adhesin. FimH is a component of the fimbrial organelle that can accommodate and display a diverse ...
Epitope prediction based on random peptide library screening has become a focus as a promising method in immunoinformatics research. Some novel software and web-based servers have been proposed in recent years and have succeeded in given test cases. However, since the number of available mimotopes with the relevant structure of template-target complex is limited, a systematic evaluation of thes...
Aquaporin-2 (AQP2), the vasopressin-regulated water channel in collecting duct principal cells, plays a key role in the regulation of body water balance. We aimed to isolate high-affinity peptide ligands that bind to immunoisolated AQP2-expressing plasma membrane (PM) or intracellular vesicle (ICV) preparations from rat kidney by the in vitro phage display technique. Immunoblotting revealed tha...
Translation of a 5-codon mini-gene encoded in Escherichia coli 23 S rRNA was previously shown to render cells resistant to erythromycin (Tenson, T., DeBlasio, A., and Mankin, A. S. (1996) Proc. Natl. Acad. Sci. U. S. A. 93, 5641-5646). Erythromycin resistance was mediated by a specific interaction of the 23 S rRNA-encoded pentapeptide with the ribosome. In the present study, peptides conferring...
An increasing number of reported cases of drug resistant Staphylococcus aureus and Pseudomonas aeruginosa, demonstrate the urgent need for new therapeutics that are effective against such and other multi-drug resistant bacteria. Antimicrobial peptides have for two decades now been looked upon as interesting leads for development of new therapeutics combating these drug resistant microbes. High-...
The voltage-gated sodium channel (VGSC) interacting peptide is of special interest for both basic research and pharmaceutical purposes. In this study, we established a yeast-two-hybrid based strategy to detect the interaction(s) between neurotoxic peptide and the extracellular region of VGSC. Using a previously reported neurotoxin JZTX-III as a model molecule, we demonstrated that the interacti...
Phage display screening allows the study of functional protein-protein interactions at the cell surface, but investigating intracellular organelles remains a challenge. Here we introduce internalizing-phage libraries to identify clones that enter mammalian cells through a receptor-independent mechanism and target-specific organelles as a tool to select ligand peptides and identify their intrace...
A phage-displayed random 7-mer disulfide bridge-constrained peptide library was used to map the surface of the RhoA GTPase and to find peptides able to recognize RhoA switch regions. Several peptide sequences were selected after four rounds of enrichment, giving a high signal in ELISA against RhoA-GDP. A detailed analysis of one such selected peptide, called R2 (CWSFPGYAC), is reported. The Rho...
