TRF1 uses a noncanonical function of TFIIH to promote telomere replication

Z Yang, K Sharma, T de Lange - Genes & Development, 2022 - genesdev.cshlp.org
Telomeric DNA challenges the replisome and requires TRF1 for efficient duplication. TRF1
recruits the BLM helicase, but BLM loss does not explain the extensive telomere fragility …

Phosphorylation of XPD drives its mitotic role independently of its DNA repair and transcription functions

E Compe, E Pangou, N Le May, C Elly, C Braun… - Science …, 2022 - science.org
The helicase XPD is known as a key subunit of the DNA repair/transcription factor TFIIH.
However, here, we report that XPD, independently to other TFIIH subunits, can localize with …

RNAP II antagonizes mitotic chromatin folding and chromosome segregation by condensin

J Lebreton, L Colin, E Chatre, P Bernard - Cell Reports, 2024 - cell.com
Condensin shapes mitotic chromosomes by folding chromatin into loops, but whether it does
so by DNA-loop extrusion remains speculative. Although loop-extruding cohesin is stalled …

Making mitotic chromosomes in a test tube

Transcription factor Sp1 regulates mitotic chromosome assembly and segregation

S Flashner, M Swift, A Sowash, AN Fahmy… - Chromosoma, 2022 - Springer
Aneuploidy is a pervasive feature of cancer cells that results from chromosome

Regulation of the mitotic chromosome folding machines

B Dekker, J Dekker - Biochemical Journal, 2022 - portlandpress.com
Over the last several years enormous progress has been made in identifying the molecular
machines, including condensins and topoisomerases that fold mitotic chromosomes. The …

Release of Histone H3K4-reading transcription factors from chromosomes in mitosis is independent of adjacent H3 phosphorylation

RJ Harris, M Heer, MD Levasseur… - Nature …, 2023 - nature.com

Molecular basis for condensin enrichment at pericentromeres

M Wang, J Zou, C Spanos, J Rappsilber, AL Marston - bioRxiv, 2024 - biorxiv.org
Faithful chromosome segregation requires packaging of the genome on both global and
