YY1 and CTCF orchestrate a 3D chromatin looping switch during early neural lineage commitment
Open accessAbstract
CTCF is an architectural protein with a critical role in connecting higher-order chromatin folding in pluripotent stem cells. Recent reports have suggested that CTCF binding is more dynamic during development than previously appreciated. Here, we set out to understand the extent to which shifts in genome-wide CTCF occupancy contribute to the 3D reconfiguration of fine-scale chromatin folding during early neural lineage commitment. Unexpectedly, we observe a sharp decrease in CTCF occupancy during the transition from naïve/primed pluripotency to multipotent primary neural progenitor cells (NPCs). Many pluripotency gene-enhancer interactions are anchored by CTCF, and its occupancy is lost in parallel with loop decommissioning during differentiation. Conversely, CTCF binding sites in NPCs are largely preexisting in pluripotent stem cells. Only a small number of CTCF sites arise de novo in NPCs. We identify another zinc finger protein, Yin Yang 1 (YY1), at the base of looping interactions between NPC-specific genes and enhancers. Putative NPC-specific enhancers exhibit strong YY1 signal when engaged in 3D contacts and negligible YY1 signal when not in loops. Moreover, siRNA knockdown of Yy1 specifically disrupts interactions between key NPC enhancers and their target genes. YY1-mediated interactions between NPC regulatory elements are often nested within constitutive loops anchored by CTCF. Together, our results support a model in which YY1 acts as an architectural protein to connect developmentally regulated looping interactions; the location of YY1-mediated interactions may be demarcated in development by a preexisting topological framework created by constitutive CTCF-mediated interactions.

TL;DR
During early neural lineage commitment, CTCF occupancy is globally pruned from pluripotent stem cells to multipotent neural progenitor cells (NPCs), while NPC-specific enhancer–gene loops are instead anchored by YY1. The paper proposes that YY1-mediated NPC looping interactions arise within a preexisting constitutive CTCF-anchored topological framework.
Key findings
- CTCF binding decreases stepwise across ES 2i, ES serum, and NPCs: 56,138, 50,185, and 28,860 sites, respectively, with 60,688 unique sites total. Of these, 26,435 were constitutive, 8,832 were “2i only,” 20,068 were “2i+Serum,” and only 1,119 were “NPC-only”; CTCF gene expression and protein levels also decreased in NPCs.
- 5C analysis identified 141 constitutive loops, 46 “2i+Serum” loops lost in NPCs, and 75 NPC-only loops. “2i+Serum” loops were enriched for “2i+Serum” CTCF sites, and the pluripotency-specific Sox2–ES enhancer loop broke concurrently with CTCF loss.
- NPC-only loops were not enriched for NPC-only CTCF binding: almost 40% of NPC-only interactions lacked CTCF anchoring, versus <5% of constitutive and <10% of “2i+serum” interactions. Instead, YY1 was strongly enriched at NPC-only loops and at NPC-specific enhancers engaged in 3D contacts, with negligible YY1 signal at NPC-specific enhancers not in loops.
- YY1 sites were less constitutive than CTCF sites (36%, 39%, and 25% constitutive across ES serum, NPCs, and pro-B cells; n = 3,474). NPC-specific enhancers were enriched in NPC-only loops when bound by YY1 without CTCF, but not when bound by CTCF without YY1. Yy1 siRNA knockdown produced >50% reduction in Yy1 expression/protein, disrupted the Sox2–enhancer loop, decreased Sox2 expression, and also reduced Klf4 and Zfp462 looping and Nes/Olig1/Olig2 expression.
Methods
- ChIP-seq was performed for CTCF in mouse ES 2i, ES serum, and NPCs, with ENCODE mouse brain CTCF data reanalyzed; RNA-seq and Western blot assessed CTCF expression/protein. YY1 and H3K27ac ChIP-seq datasets were also analyzed.
- 5C with high-throughput sequencing generated fine-scale chromatin architecture maps at ~4- to 12-kb matrix resolution across >7 Mb of the mouse genome, using n = 2 biological replicates and reanalyzed published 5C libraries. A new computational pipeline used donut and lower-left background filters, logistic-distribution P-values, interaction scores, and seven looping classes; top five dynamic classes had empirical FDR <15%.
- Yy1 knockdown in NPCs used Dharmacon siRNA pools at 20 nM for 78 h, followed by Western blot, qPCR, and 3C/5C analysis.
Limitations
- Stated: the authors cannot rule out that heterogeneity in ENCODE brain tissues contributed to the aggregate CTCF decrease, though their NPC cultures were >90% SOX2 positive. The role of YY1 in ES cells remains unclear because of possible greater ES reliance on CTCF, different ChIP methods between ES and NPC YY1 datasets, or a different regulatory role for YY1 in the two cell types.
- Stated: technical issues with poor library complexity prevented high-complexity 5C maps at Olig1, Olig2, and Nes after Yy1 knockdown; for those loci, only expression reductions were observed.
- Evident: 5C covered selected regions (>7 Mb) rather than the whole genome, and the Yy1 perturbation was an siRNA knockdown with >50% reduction rather than a complete knockout, so some conclusions about YY1’s architectural role remain correlative or partial.

“Given the known function of CTCF and YY1 in chromatin organization, the results raise the possibility that these R-loops coordinate post-transcriptional pathways across various biological contexts [44,52,53].”

“This pattern may reflect the dynamic process in which cohesin moves along DNA to extrude chromatin loops and becomes anchored or paused at CTCF binding sites, while YY1 helps bridge distal enhancers and promoters [39].”

“…(defined as the proportion of contacts crossing a particular genomic region compared with adjacent loci), as we and others have previously linked changes in chromatin insulation to changes in gene expression in mouse neural differentiation (Beagan et al. 2017; Bonev 2017; Noack et al. 2022).”
YY1 in hematopoietic stem cells: epigenetic regulation, chromatin architecture, and aging
Wang, Y., & Pan, X. (2026) · Current Opinion in Hematology · doi:10.1097/moh.0000000000000925
“Understanding YY1-dependent chromatin architecture architecture may provide a mechanistic framework for HSC aging and reveal strategies to restore youthful hematopoiesis.”

Yin Yang 1 Specifically Supports the Development of Olig2 Positive Cerebellar Astrocytes
Zarei‐Kheirabadi, M., Tyc, K. M., Dain, L., Kheirabadi, M. A., Hanco, J., Mockenhaupt, K., Munir, S., McQuiston, A. R., Singh, S. K., & Kordula, T. (2026) · Glia · doi:10.1002/glia.70185
“YY1 regulates the development of the neuroepi-thelium (Dong and Kwan 2020), orchestrates chromatin looping during neural lineage commitment (Beagan et al. 2017; Weintraub et al. 2017), and supports proliferation and survival of neural progenitor cells (Zurkirchen et al. 2019).”

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 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
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.
