Conservation of the Irga6 surface. The molecular surface of Irga6-M173A [14] is shown. ConSurf [62,63] was used with an alignment of IRGs (Additional file 2) to calculate the conservation score of Irga6 residues. Conserved residues are coloured in magenta, variable in cyan. (a to f) The same orientations of the molecule are shown as in Figure 1.
