Naturally Occurring Polymorphisms of the Mouse Gammaretrovirus Receptors CAT-1 and XPR1 Alter Virus Tropism and Pathogenicity

Phylogenetic tree of Mus. Blue arrows indicate the species that have acquired XP-MLV ERVs, and the subset that have predominantly X-MLVs. 4 colored boxes identify the mice carrying the 4 restrictive Xpr1 alleles; all other species carry the permissive Xpr1sxv.
