Fig. 5From: The UT family of MHC class I loci unique to non-eutherian mammals has limited polymorphism and tissue specific patterns of expression in the opossumPredicted structural model of ModoUT5 binding groove identifying the sites of positive selection in comparison to ModoUA1. a and b Top and side views of predicted structural model of ModoUT5. Red and yellow shading represent sites under positive selection, with red significant at p < 0.005 and yellow at p < 0.05. c and d Top and side views of predicted structural model of ModoUA1, with yellow shading representing sites under positive selectionBack to article page
