CCCTC-binding factor N-terminal domain regulates clustered protocadherin gene expression by enhancing cohesin processivityThe Journal of biological chemistry · 2025
Summary (written by the submitters)
CTCF structures 3D genome folding by anchoring or forestalling cohesin loop extrusion, but the exact mechanism remains obscure. Here, using clustered protocadherins (cPcdh) as model genes, we report that CTCF stabilizes or facilitates cohesin loop extrusion by enhancing its processivity. Specifically, we show that, compared with the Pcdh alpha and gamma clusters, the Pcdh beta cluster is greatly affected upon CTCFY226A/F228A mutation in the N-terminal domain.
Read the full summary ↓
Given the long-range distance of the Pcdh beta cluster from the distal enhancer, this finding has interesting implications in CTCF regulation of cohesin processivity along the linear chromatin during DNA loop extrusion. In particular, the effect on cohesin processivity upon CTCFY226A/F228A mutation is conspicuously similar to that of WAPL overexpression, demonstrating that, contrary to the general view of blocking or forestalling cohesin, CTCF actually enhances or facilitates cohesin loop extrusion.

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 GSE285578_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 PRJNA1204916 and SRA study SRP554649. Searching any of these in the dataset finder brings you back here.

Study design
20 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 20 sample titles: 20 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.
