Swi/Snf chromatin remodeling regulates transcriptional interference and gene repression

|
By Kaitlin Morse, Barker Hall, Sarah Swerdlow, Jessica Leslie
| Cell Press Verified
Highlights • Unbiased genetic approach reveals a role for yeast Swi/Snf in promoter repression • Swi/Snf represses promoters subject to upstream transcriptional readthrough • Repression is associated with Swi/Snf-dependent nucleosome remodeling • Swi/Snf-dependent repression regulates protein levels for LUTI-regulated genes Summary Alternative transcription start sites can affect transcript isoform diversity and translation levels.

Integrated genomic analysis reveals key features of long undecoded transcript isoform-based gene repression

|
By Amy Tresenrider, Barker Hall, Kaitlin Morse, Victoria Jorgensen
| Cell Press Verified
Highlights • Long-read RNA-seq reveals 5′-extended mRNAs as candidate LUTIs in yeast meiosis • Majority of the LUTIs are regulated by a cell-fate-instructive transcription factor • LUTI-based translational repression depends on uORFs • Chromatin changes and LUTI expression predict LUTI-based transcriptional repression Summary Long undecoded transcript isoforms (LUTIs) represent a class of non-canonical mRNAs that downregulate gene expression through the combined act of transcriptional and...
