Dynamic imaging of nascent RNA reveals general principles of transcription dynamics and stochastic splice site selection

Y Wan, DG Anastasakis, J Rodriguez, M Palangat… - Cell, 2021 - cell.com
The activities of RNA polymerase and the spliceosome are responsible for the heterogeneity
in the abundance and isoform composition of mRNA in human cells. However, the dynamics …

Real-time imaging of a single gene reveals transcription-initiated local confinement

T Germier, S Kocanova, N Walther, A Bancaud… - Biophysical journal, 2017 - cell.com

A ubiquitous disordered protein interaction module orchestrates transcription elongation

K Cermakova, J Demeulemeester, V Lux, M Nedomova… - Science, 2021 - science.org
During eukaryotic transcription elongation, RNA polymerase II (RNAP2) is regulated by a
chorus of factors. Here, we identified a common binary interaction module consisting of TFIIS …

Overview of CDK9 as a target in cancer research

The pausing zone and control of RNA polymerase II elongation by Spt5: Implications for the pause-release model

N Fong, RM Sheridan, S Ramachandran, DL Bentley - Molecular cell, 2022 - cell.com
The pause-release model of transcription proposes that 40–100 bases from the start site
RNA Pol II pauses, followed by release into productive elongation. Pause release is …

Alternative RNA structures formed during transcription depend on elongation rate and modify RNA processing

T Saldi, K Riemondy, B Erickson, DL Bentley - Molecular cell, 2021 - cell.com
Most RNA processing occurs co-transcriptionally. We interrogated nascent pol II transcripts
by chemical and enzymatic probing and determined how the" nascent RNA structureome" …

Transcriptional control by premature termination: a forgotten mechanism

K Kamieniarz-Gdula, NJ Proudfoot - Trends in Genetics, 2019 - cell.com
