ZSCAN4 is transiently expressed in a small subset of embryonic stem cells and early embryos, where it regulates repetitive DNA to support genome integrity and plasticity.
- Why it matters: The field needs a unifying explanation for how ZSCAN4 promotes genome stability without acting as a classical stemness factor.
- What they did: Mechanistic work shows ZSCAN4 preferentially acts at repetitive DNA, supporting telomere maintenance and elongation and enabling brief chromatin relaxation at microsatellite-rich and 2C-associated loci.
- The result: The proposed model is that ZSCAN4 acts as a transient genome reset factor during zygotic genome activation, 2C-like transitions, and cellular reprogramming, while preserving long-term genome integrity.
