Web12 apr. 2024 · Summary. Exons are regions of DNA that are transcribed to RNA and retained after introns are spliced out. However, the term “exon” is often misused as synonymous to “protein coding,” including in some literature and textbook definitions. In contrast, only a fraction of exonic sequences are protein coding (<30% in humans). Web30 aug. 2024 · Results: We employed position-weight matrices to obtain a comprehensive updated list of minor introns, consisting of 722 mouse and 770 human minor introns. These can be found in the Minor Intron DataBase (MIDB). Besides identification of 99% of the minor introns found in the U12DB, we also discovered ~ 150 new MIGs.
