Figure 2From: The evolutionary history of the SAL1 gene family in eutherian mammalsLoss of SAL1 orthologous gene in human and Neandertal genomes. The underlined A represents the G-to-A substitution in the donor site of the second intron in human and Neandertal genomic sequences, resulting in a shift in the ORF and in the pseudogenization of the gene in the two species.Back to article page
