Figure 4

An example of HIV-human protein interaction graph. The white, blue, and green circles represent the target, HIV-1, and other human proteins, respectively. Information of any of the protein can be obtained on the right panel by clicking on that protein circle. The triangles each represent a PPI key phrase based on one research article. By clicking on one of the triangles, the users can obtain more detailed information on the right panel, including a short description of the interaction, a PubMed hyperlink to the original publication, and hyperlinks to the annotations of the interacting proteins. The dashed lines indicate HPRD- and BIND-based interactions between human proteins. The circled dashed lines indicate self-interactions. The semi-circles around each protein node indicate the presence of orthologous proteins in the non-human organisms. The entire graph can be zoomed in and out by holding and moving the right mouse click. The graph can also be moved along by holding and moving the left mouse click.
