The structural basis for cohesin–CTCF-anchored loops
Open accessAbstract
Cohesin catalyses the folding of the genome into loops that are anchored by CTCF1. The molecular mechanism of how cohesin and CTCF structure the 3D genome has remained unclear. Here we show that a segment within the CTCF N terminus interacts with the SA2–SCC1 subunits of human cohesin. We report a crystal structure of SA2–SCC1 in complex with CTCF at a resolution of 2.7 Å, which reveals the molecular basis of the interaction. We demonstrate that this interaction is specifically required for CTCF-anchored loops and contributes to the positioning of cohesin at CTCF binding sites. A similar motif is present in a number of established and newly identified cohesin ligands, including the cohesin release factor WAPL2,3. Our data suggest that CTCF enables the formation of chromatin loops by protecting cohesin against loop release. These results provide fundamental insights into the molecular mechanism that enables the dynamic regulation of chromatin folding by cohesin and CTCF. The crystal structure of the SA2–SCC1 subunits of human cohesin in complex with CTCF reveals the molecular basis of the cohesin–CTCF interaction that enables the dynamic regulation of chromatin folding.
Overview
AI snapshot
Written from the paper’s full text.
TL;DR
CTCF’s N-terminal YxF motif binds the SA2–SCC1 “conserved essential surface” (CES), and a 2.6 Å crystal structure explains the interface. Disrupting this interface abolishes CTCF-anchored loops while leaving TAD-like structures largely present, suggesting CTCF stabilizes cohesin at loop anchors rather than merely acting as a passive barrier.
Key findings
- CTCF residues 222–231 bind SA2–SCC1 with Kd = 1.04 ± 0.20 μM; Y226 and F228 are the lead anchoring residues, and Y226A/F228A abolish binding in GST pulldowns.
- In HAP1 cells with endogenous CTCF Y226A F228A, Hi-C loop calls drop from 2756 in wild type to 98 in mutant cells; TAD-like structures remain but have less-clear edges.
- FRAP shows cohesin is more mobile in CTCF Y226A F228A cells, and ChIP-qPCR/ChIP-seq show reduced cohesin at CTCF sites, while CTCF binding itself is largely unaffected.
- WAPL competes with CTCF for the SA2–SCC1 CES; the CTCF peptide binds more strongly than WAPL peptides (WAPL 423–463 Kd ≈ 32.8 μM), and RNA-seq shows >2000 genes affected by the CTCF mutation.
Methods
- Biochemical binding assays: GST pulldowns, isothermal titration calorimetry, and peptide arrays using SA2–SCC1 and mutant complexes.
- Structural analysis: crystals of SA2–SCC1 in complex with a CTCF 222–231 peptide; structure determined by molecular replacement at 2.6 Å (Rwork/Rfree 0.25/0.27).
- Cell and genome-wide assays: CRISPR/Cas9-generated HAP1 CTCF Y226A F228A cells, HaloTagged SCC1 FRAP, Hi-C, ChIP-qPCR/ChIP-seq, and RNA-seq.
Limitations
- The paper does not include a dedicated limitations section.
- Evident from the text: key cellular conclusions rely on the human haploid HAP1 cell line and a single CTCF interface mutant (Y226A F228A), with no in vivo organismal validation.
- Evident from the text: CTCF depletion was lethal in both control and CTCF Y226A F228A HAP1 cells, so essential CTCF functions independent of CES engagement and CTCF-anchored loops remain unresolved.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-07, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-07 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
