WebJun 1, 2024 · Loop extrusion is a motor-driven process by which a protein complex gradually grows and enlarges chromatin/DNA loops by reeling in the chromatin fiber or DNA. This unusual motor activity is primarily ascribed to a widely conserved class of protein complexes known as structural maintenance of chromosomes (SMC) complexes, which … WebDec 12, 2024 · DNA compaction by cohesin requires ATP hydrolysis, and is force-sensitive. This compaction is processive over tens of kilobases (kb) at an average rate of 0.5 kb per second. Compaction of double-tethered DNA suggests that a cohesin dimer extrudes DNA loops bidirectionally.
