The Sox family of genes shares a high sequence similarity with the HMG box region of the human Y chromosomal gene, SRY. We used highly degenerate primers to clone and sequence seven Eremias breuchleyi Sox genes (EbSox2, EbSox3, EbSox4, EbSox11, EbSox12, EbSox14 and EbSox21). A database search for the cloned sequences revealed the following percentage identity with the homologous human SOX genes: EbSox2 = 96%, EbSox3 = 88%, EbSox4 = 94%, EbSox11 = 99%, EbSox12 = 96%, EbSox14 = 98%, EbSox21 = 97%. Cluster analysis indicates that they seem to belong to group B and group C of Sox gene family, respectively.
