Can a gene start with an intron

WebIn many eukaryotes, including mammals, plants, yeast, and insects, introns can increase gene expression without functioning as a binding site for transcription factors. This phenomenon was termed 'intron-mediated enhancement'. Introns can increase transcript levels by affecting the rate of transcription, nuclear export, and transcript stability. WebNov 18, 2024 · The integration of the TetR aptamer-controlled intron CI from FLuc into a similar position of a GFP gene resulted in only 2-fold regulation (data not shown).
