Clustering paralogues and orthologues of 4 flanking proteins. We used clustering to identify the paralogues and orthologues of the 4 flanking proteins (a: slc29a3, b: unc5b, c: pcbd1, d: sgpl1) in 4 species (mouse, rat, human and chicken). The result beyond indicates these Pldi-Ak158810 loci surrounding regions linkaged in these 4 species and these 4 flanking genes have been free from duplication of their paralogues since the time of their cen-ancestor. Sgpl1 doesn't contain a paralogue and it has the same topological structure as the other genes.
