Genome folding through loop extrusion by SMC complexes

IF Davidson, JM Peters - Nature reviews Molecular cell biology, 2021 - nature.com
Genomic DNA is folded into loops and topologically associating domains (TADs), which
serve important structural and regulatory roles. It has been proposed that these genomic …

SMC complexes: from DNA to chromosomes

F Uhlmann - Nature reviews Molecular cell biology, 2016 - nature.com
SMC (structural maintenance of chromosomes) complexes—which include condensin,
cohesin and the SMC5–SMC6 complex—are major components of chromosomes in all …

3D genomics across the tree of life reveals condensin II as a determinant of architecture type

C Hoencamp, O Dudchenko, AMO Elbatsh… - Science, 2021 - science.org
We investigated genome folding across the eukaryotic tree of life. We find two types of three-
dimensional (3D) genome architectures at the chromosome scale. Each type appears and …

Condensin-based chromosome organization from bacteria to vertebrates

T Hirano - Cell, 2016 - cell.com
Condensins are large protein complexes that play a central role in chromosome
organization and segregation in the three domains of life. They display highly characteristic …

Structural basis for a safety-belt mechanism that anchors condensin to chromosomes

M Kschonsak, F Merkel, S Bisht, J Metz, V Rybin… - Cell, 2017 - cell.com
Condensin protein complexes coordinate the formation of mitotic chromosomes and thereby
ensure the successful segregation of replicated genomes. Insights into how condensin …

Establishment of dsDNA-dsDNA interactions by the condensin complex

M Tang, G Pobegalov, H Tanizawa, ZA Chen… - Molecular cell, 2023 - cell.com
Condensin is a structural maintenance of chromosomes (SMC) complex family member
thought to build mitotic chromosomes by DNA loop extrusion. However, condensin variants …

HEAT repeats–versatile arrays of amphiphilic helices working in crowded environments?

SH Yoshimura, T Hirano - Journal of cell science, 2016 - journals.biologists.com
Cellular proteins do not work in isolation. Instead, they often function as part of large
macromolecular complexes, which are transported and concentrated into specific cellular …

[HTML][HTML] SMC complexes: Lifting the lid on loop extrusion

TL Higashi, F Uhlmann - Current opinion in cell biology, 2022 - Elsevier
Loop extrusion has emerged as a prominent hypothesis for how SMC complexes shape
chromosomes–single molecule in vitro observations have yielded fascinating images of this …

Molecular mechanism of condensin I activation by KIF4A

EE Cutts, D Tetiker, E Kim, L Aragon - The EMBO Journal, 2024 - embopress.org
During mitosis, the condensin I and II complexes compact chromatin into chromosomes.
Loss of the chromokinesin, KIF4A, results in reduced condensin I association with …

Structural basis of an asymmetric condensin ATPase cycle
