Superimposition of UDP and pranlukast within the putative GPR17 binding pockets. The picture shows the superimposition of UDP (in red) with the three docking poses of pranlukast (CI, in blue; CII, in green; CIII, in gray). For each simulation, the correspondent target residue R255, here highlighted with arrows, is reported in the same colors of either UDP or pranlukast. The hypothetical interactions between R255 and ligands are represented by white dotted lines.
