Report on how a telomere-associated protein regulates non-telomeric DNA structures to preserve muscle stem cell identity and support regeneration.
Key Takeaways
- Rather than triggering telomere degradation or cell death when depleted
- TRF2 exerts this control by binding non-telomeric genomic regions enriched with G-quadruplex secondary DNA structures
- Researchers discovered through lab tests that TRF2 levels rise and fall precisely during these transitions
