Structural and interaction analysis of glycoprotein VI-binding peptide selected from a phage display library.

ABSTRACT: Glycoprotein VI (GPVI) is a major collagen receptor on the platelet surface that recognizes the glycine-proline-hydroxyproline (GPO) sequence in the collagen molecule and plays a crucial role in thrombus formation. Inhibitors that block the interaction of GPVI with collagen have potential for use as antithrombotic drugs. For low molecular weight drug design for GPVI, it is essential to obtain precise structural and interaction information about GPVI-binding ligands. However, experimentally obtained structural and interaction information of small ligands, such as peptides, in the GPVI-bound state has not been reported. In this study, by screening a phage-displayed peptide library, we discovered a novel peptide ligand (pep-10L; YSDTDWLYFSTS) without any similarities to the sequence of collag
