Structure of the cohesin loader Scc2

Nature Communications, 2017
The cohesin complex maintains genome integrity by ensuring correct sister-chromatid segregation during mitosis and meiosis. Here, Chaoet al. present a pseudo-atomic model of the full-length Scc2–Scc4 cohesin loader complex and reveal key Scc2 surfaces ...

A global view of substrate phosphorylation and dephosphorylation during budding yeast mitotic exit

Microbial Cell, 2018
The cell cycle is the process by which a cell duplicates its DNA during S-phase and divides its chromosomes during M-phase, creating two genetically identical daughter cells.

Recombination and chromosome segregation

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2004
Abstract The duplication of DNA and faithful segregation of newly replicated chromosomes at cell division is frequently dependent on recombinational processes. The rebuilding of broken or stalled replication forks is universally dependent on homologous recombination proteins.

Organization and segregation of bacterial chromosomes [PDF]

Nature Reviews Genetics, 2013
The bacterial chromosome must be compacted more than 1,000-fold to fit into the compartment in which it resides. How it is condensed, organized and ultimately segregated has been a puzzle for over half a century. Recent advances in live-cell imaging and genome-scale analyses have led to new insights into these problems. We argue that the key feature of

CHROMOSOME SEGREGATION MECHANISMS [PDF]

Genetics, 1974
ABSTRACT Most aspects of chromosome distribution to the daughter cells in meiosis and mitosis are now understood, at the cellular level. The most striking evidence that the proposed explanation is valid is that it correctly predicts the outcome of experiments on living cells in which the experimenter (1) can determine the distribution of

Bacterial chromosome segregation

Frontiers in Bioscience, 2012
Dividing cells have mechanisms to ensure that their genomes are faithfully segregated into daughter cells. In bacteria, the description of these mechanisms has been considerably improved in the recent years. This review focuses on the different aspects of bacterial chromosome segregation that can be understood thanks to the studies performed with model

Cdc14 and PP2A Phosphatases Cooperate to Shape Phosphoproteome Dynamics during Mitotic Exit

Cell Reports, 2019
Summary: Temporal control over protein phosphorylation and dephosphorylation is crucial for accurate chromosome segregation and for completion of the cell division cycle during exit from mitosis. In budding yeast, the Cdc14 phosphatase is thought to be a

Autism and mild epilepsy associated with a de novo missense pathogenic variant in the GTPase effector domain of DNM1

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView., 2023
Abstract Dynamin 1 is a GTPase protein involved in synaptic vesicle fission, which facilitates the exocytosis of neurotransmitters necessary for normal signaling. Pathogenic variants in the DNM1 gene are associated with intractable epilepsy, often manifested as infantile spasms at onset, developmental delay, and a movement disorder, and are located in ...

Bacterial Chromosome Organization and Segregation [PDF]

Cold Spring Harbor Perspectives in Biology, 2010
Bacterial chromosomes are generally approximately 1000 times longer than the cells in which they reside, and concurrent replication, segregation, and transcription/translation of this crowded mass of DNA poses a challenging organizational problem. Recent advances in cell-imaging technology with subdiffraction resolution have revealed that the bacterial
