Abstract excerpt
The product of ubiquitin genes is a small protein involved in intracellular sorting of other proteins. The locus consists of tandemly arrayed, uninterrupted copies of the gene. As several studies have noted, the Polyubiquitin locus is a model system for studying concerted evolution. While the protein is among the most conserved known, individual copies within an organism show variation in nucleotide sequence...
