Condensin accelerates long-range intra-chromosomal interactions - Nature Communications Long‑range chromosome encounters in cells are hard to quantify. Here, the authors induce artificial contacts in yeast and show that intra‑chromosomal interactions form faster than inter‑chromosomal ones in G1 yeast, driven by condensin‑mediated loop extrusion.

Condensin accelerates long‑range intra‑chromosomal interactions in budding yeast. Using CICI to measure encounter times across loci, the study provides a dynamic view of chromatin motion beyond static 3C snapshots. #NatureCommunications #Chromatin #YeastResearch
