Alu repeats have played important roles in the evolution of (alternative) splicing via exonization and in other ways. In this paper, we show that they mediate interactions across exons to loop them out. Alus inserted this way in evolution render exons alternative. bit.ly/4t8Yahh 1/2

Alu-mediated RNA duplexes are associated with widespread exon skipping across primate transcriptomes - Genome Biology
Alternative splicing patterns have diverged rapidly during vertebrate evolution. By integrating genome-wide predictions of stable RNA duplexes, alternative splicing profiles, and proximity ligation-de...
