Transposons contribute to splice-isoform diversity in the Drosophila brain

The extraordinary complexity of the brain depends in part on the vast diversity of mRNA isoforms it expresses, often in a cell-type specific manner.

The extraordinary complexity of the brain depends in part on the vast diversity of mRNA isoforms it expresses, often in a cell-type specific manner. In a recent study, we found that intronic transposable elements (TEs) are spliced into neural transcripts and diversify the splice…
