Structural maintenance of chromosomes (SMC) complexes organize the genome via DNA loop extrusion. Although some SMCs were reported to do so symmetrically, reeling DNA from both sides into the extruded DNA loop simultaneously, others perform loop extrusion asymmetrically toward on

Eukaryotes carry three types of structural maintenance of chromosome (SMC) protein complexes, condensin, cohesin, and SMC5/6, which are ATP-dependent motor proteins that remodel the genome via DNA loop extrusion (LE). SMCs modulate DNA supercoiling but remains incompletely unders

Testing pseudotopological and nontopological models for SMC-driven DNA loop extrusion against roadblock-traversal experiments (Scientific Reports, (2023), 13, 1, (8100), 10.1038/s41598-023-35359-2)
Correction to: Scientific Reports, published online 19 May 2023 The original version of this Article contained an error in Figure 1b-1, where the fore- and background order of the strands “DNA” (in black) and “Brn1 Kleisin” (in green), were switched. The original Figure 1 and acc

In eukaryotes, genomic DNA is extruded into loops by cohesin1. By restraining this process, the DNA-binding protein CCCTC-binding factor (CTCF) generates topologically associating domains (TADs)2,3 that have important roles in gene regulation and recombinati

DNA loop extrusion by structural-maintenance-of-chromosome (SMC) complexes has emerged as a primary organizing principle for chromosomes. The mechanism by which SMC motor proteins extrude DNA loops is still unresolved and much debated. The ring-like structure of SMC complexes pro
