Conserved synteny around Nme1 and Nme2 loci in tetrapods. The syntenic relationships of genes in the vicinity of human NME1 and NME2 linked genes were established using CASSIOPE. For clarity reasons, only selected genes are shown. (A) Graphical view of syntenic relationships in chicken, human, mouse, cow, opossum, and anole lizard Nme1 and Nme2 loci vicinity. Only one Nme2 was found in Xenopus tropicalis (B) Location of each marker on the corresponding numbered chromosome or scaffold.
