Epigenetically Mediated Ciliogenesis and Cell Cycle Regulation, and Their Translational Potential

open access: yesCells, 2021
Primary cilia biogenesis has been closely associated with cell cycle progression. Cilia assemble when cells exit the cell cycle and enter a quiescent stage at the post-mitosis phase, and disassemble before cells re-enter a new cell cycle.

A Systemic Receptor Network Triggered by Human cytomegalovirus Entry [PDF]

open access: yes, 2010
Virus entry is a multistep process that triggers a variety of cellular pathways interconnecting into a complex network, yet the molecular complexity of this network remains largely unsolved.

DNA topoisomerase III localizes to centromeres and affects centromeric CENP-A levels in fission yeast. [PDF]

open access: yesPLoS Genetics, 2013
Centromeres are specialized chromatin regions marked by the presence of nucleosomes containing the centromere-specific histone H3 variant CENP-A, which is essential for chromosome segregation.

CUL-2LRR-1 and UBXN-3 drive replisome disassembly during DNA replication termination and mitosis [PDF]

open access: yes, 2017
Replisome disassembly is the final step of DNA replication in eukaryotes, involving the ubiquitylation and CDC48-dependent dissolution of the CMG helicase (CDC45-MCM-GINS).

Metaphase chromosome structure is dynamically maintained by condensin I-directed DNA (de)catenation

open access: yeseLife, 2017
Mitotic chromosome assembly remains a big mystery in biology. Condensin complexes are pivotal for chromosome architecture yet how they shape mitotic chromatin remains unknown.

The Modular Circuitry of Apicomplexan Cell Division Plasticity

open access: yesFrontiers in Cellular and Infection Microbiology, 2021
The close-knit group of apicomplexan parasites displays a wide variety of cell division modes, which differ between parasites as well as between different life stages within a single parasite species. The beginning and endpoint of the asexual replication

PABPN1 Couples the Polyadenylation and Translation of Maternal Transcripts to Mouse Oocyte Meiotic Maturation

open access: yesAdvanced Science, EarlyView.
This study reveals that cytoplasmic PABPN1 is essential for mouse oocyte meiotic maturation by coordinating polyadenylation, translation, and degradation of maternal mRNAs. Pabpn1 knockout disrupts CDK1 activation, spindle formation, and chromosome alignment by impairing maturation‐promoting factor (MPF) regulation and BTG4‐mediated deadenylation ...

Weaving a pattern from disparate threads: lamin function in nuclear assembly and DNA replication [PDF]

open access: yes, 1994
The major residual structure that remains associated with the nuclear envelope following extraction of isolated nuclei or oocyte germinal vesicles with non-ionic detergents, nucleases and high salt is the lamina (Fawcett, 1966; Aaronson and Blobel ...

Importin-9 wraps around the H2A-H2B core to act as nuclear importer and histone chaperone. [PDF]

open access: yes, 2019
We report the crystal structure of nuclear import receptor Importin-9 bound to its cargo, the histones H2A-H2B. Importin-9 wraps around the core, globular region of H2A-H2B to form an extensive interface.

The JmjC domain protein Epe1 prevents unregulated assembly and disassembly of heterochromatin

open access: yesEMBO Journal, 2007
Heterochromatin normally has prescribed chromosomal positions and must not encroach on adjacent regions. We demonstrate that the fission yeast protein Epe1 stabilises silent chromatin, preventing the oscillation of heterochromatin domains.
