Sister Chromatid Cohesion Remodeling and Meiotic Recombination [PDF]

open access: yesCell Cycle, 2006
Proper control of cohesion along the chromosome arms is essential for segregation of homologous chromosomes in meiosis. In a recent study we reported that Tid1p, a protein previously implicated in recombination, is required for resolution of Mcd1p-dependent cohesion in meiosis. Here we demonstrate that Pds5p and Dmc1p promote this cohesion.

Structure of the Pds5-Scc1 Complex and Implications for Cohesin Function

open access: yesCell Reports, 2016
Sister chromatid cohesion is a fundamental prerequisite to faithful genome segregation. Cohesion is precisely regulated by accessory factors that modulate the stability with which the cohesin complex embraces chromosomes.

Aurora A-dependent CENP-A phosphorylation at inner centromeres protects bioriented chromosomes against cohesion fatigue

open access: yesNature Communications, 2018
Sustained spindle tension applied to sister centromeres during mitosis leads to loss of sister chromatid cohesion which is known as cohesion fatigue.

PHB2 Protects Sister-Chromatid Cohesion in Mitosis [PDF]

open access: yesCurrent Biology, 2007
Cohesion between sister chromatids is essential for proper chromosome segregation in mitosis. In vertebrate mitotic cells, most cohesin is removed from the chromosome arms [1-4], but centromeric cohesin is protected by shugoshin until the onset of anaphase [5].

A new thermosensitive smc-3 allele reveals involvement of cohesin in homologous recombination in C. elegans.

open access: yesPLoS ONE, 2011
The cohesin complex is required for the cohesion of sister chromatids and for correct segregation during mitosis and meiosis. Crossover recombination, together with cohesion, is essential for the disjunction of homologous chromosomes during the first ...

MITF maintains genome stability in nonmelanocyte lineages

open access: yesMolecular Oncology, EarlyView.
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

Homologous recombination, sister chromatid cohesion, and chromosome condensation in mammalian meiosis [PDF]

open access: yes, 2002
In the life cycle of sexually reproducing eukaryotes, haploid and diploid generations of cells alternate. Two types of cell division occur in such a life cycle: mitosis and meiosis. They are compared in chapter 1 .

Automated FRAP microscopy for high‐throughput analysis of protein dynamics in chromatin organization and transcription

open access: yesFEBS Open Bio, EarlyView.
RoboMic is an automated confocal microscopy pipeline for high‐throughput functional imaging in living cells. Demonstrated with fluorescence recovery after photobleaching (FRAP), it integrates AI‐driven nuclear segmentation, ROI selection, bleaching, and analysis.

Cohesin: Functions beyond sister chromatid cohesion [PDF]

open access: yesFEBS Letters, 2013
Faithful segregation of chromosomes during mitosis and meiosis is the cornerstone process of life. Cohesin, a multi‐protein complex conserved from yeast to human, plays a crucial role in this process by keeping the sister chromatids together from S‐phase to anaphase onset during mitosis and meiosis.
