Short interspersed elements (SINEs) are retrotransposons that have accumulated in genomes through a ?copy-and-paste? mechanism. Once inserted, these sequences have the potential to gain novel functions, including regulating gene expression. Here, we demonstrate the unexpected finding that independently evolved SINEs have accumulated in the 3?-untranslated regions of orthologous human and mouse genes. We demonstrate that, in some cases, this has resulted in their regulating gene expression by Staufen-mediated mRNA decay (SMD) in human and mouse myoblasts. Thus, SINE-directed SMD has convergently evolved to regulate myoblast metabolism. This represents an example of the convergent evolution of posttranscriptional gene regulation using SINEs.
