LEDGF/p75 promotes transcriptional pausing through preventing SPT5 phosphorylationScience advances · 2025
Summary (written by the submitters)
The transcriptional progression is regulated by SPT5, which is involved in both promoter-proximal RNA polymerase II (Pol II) pausing and elongation, which serve as rate-limiting steps in metazoan. However, the mechanism for SPT5 coordinating these processes remains unclear. Here we report that the disordered sub-regions within SPT5 contain a prion-like domain (PLD) that is required for Pol II pausing, while the phosphorylation site-rich domain (PRD) is essential for transcript elongation.
Read the full summary ↓
Mechanically, SPT5-PLD helps stabilize Pol II pausing by preventing SPT5-PRD phosphorylation mediated by the super elongation complex (SEC). SPT5-PLD also maintains Pol II pausing by recruiting a newly identified transcriptional pause regulator, PSIP1, which inhibits phosphorylation required for elongation. Additionally, SPT5-PLD prevents premature release of Pol II pausing through PSIP1’s IBD domain by counteracting SEC. Our results demonstrate that SPT5 possesses intrinsic characteristics that balance the transcriptional process by preventing premature pause release and promoting progression to elongation.

This dataset
Download · which file do I need?

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE250380_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: Look for peak files (.bed, .narrowPeak) and signal tracks (.bigWig) among the supplementary files; the raw reads are on ENA.

Also filed as BioProject PRJNA1053782 and SRA study SRP478462. Searching any of these in the dataset finder brings you back here.

Study design
24 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 24 sample titles: 24 distinct titles with little repetition. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
