Abstract:
:From the extensive analysis, we identified three highly conserved sequence segments in HCV NS5A proteins and one binding motif in human proteins. The binding motif of human proteins often forms a full helix or an extended strand-loop structure, and is in good agreement with the experimental findings of previous studies.
