Model of ICAM-4.
Domain 1 is at the top of the figure. (A) Model of ICAM-4 (Cα trace in bold) is overlaid on the equivalent trace for the crystal structure of ICAM-2 (thin lines). (B) Ribbon diagram of the modeled ICAM-4 structure, with β strands labeled A-G and the residues mutated in this study highlighted.
