Rad53 checkpoint kinase regulation of DNA replication fork rate via Mrc1 phosphorylation

open access: yeseLife, 2021
The Rad53 DNA checkpoint protein kinase plays multiple roles in the budding yeast cell response to DNA replication stress. Key amongst these is its enigmatic role in safeguarding DNA replication forks.

Dynamic chromatin regulatory programs during embryogenesis of hexaploid wheat

open access: yesGenome Biology, 2023
Background Plant and animal embryogenesis have conserved and distinct features. Cell fate transitions occur during embryogenesis in both plants and animals. The epigenomic processes regulating plant embryogenesis remain largely elusive.

Developmental enhancers and chromosome topology

open access: yesScience, 2018
Developmental enhancers mediate on/off patterns of gene expression in specific cell types at particular stages during metazoan embryogenesis. They typically integrate multiple signals and regulatory determinants to achieve precise spatiotemporal ...

Cell-Cycle Regulation of Dynamic Chromosome Association of the Condensin Complex

open access: yesCell Reports, 2018
Summary: Eukaryotic cells inherit their genomes in the form of chromosomes, which are formed from the compaction of interphase chromatin by the condensin complex. Condensin is a member of the structural maintenance of chromosomes (SMC) family of ATPases,

Human RAD51 paralogue SWSAP1 fosters RAD51 filament by regulating the anti-recombinase FIGNL1 AAA+ ATPase

open access: yesNature Communications, 2019
RAD51 assembly on single-stranded DNAs is an important step in the homology-dependent repair of DNA damage. Here authors reveal a role for the human RAD51 paralogue, SWSAP1, as a regulator of RAD51 assembly, by antagonizing RAD51 remodeller, FIGNL1 AAA +

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

open access: yesMicrobial 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.

The 160 bp insertion in the promoter of Rht-B1i plays a vital role in increasing wheat height

open access: yesFrontiers in Plant Science, 2016
The extensive use of two alleles (Rht-B1b and Rht-D1b) at the Rht-1 locus in wheat allowed dramatic increases in yields, triggering the so-called Green Revolution. Here, we found that a new natural allelic variation (Rht-B1i) containing a single missense

Exploring lipid diversity and minimalism to define membrane requirements for synthetic cells

open access: yesFEBS Letters, EarlyView.
Designing the lipid membrane of synthetic cells is a complex task, in which its various roles (among them solute transport, membrane protein support, and self‐replication) should all be integrated. In this review, we report the latest top‐down and bottom‐up advances and discuss compatibility and complexity issues of current engineering approaches ...

Plasmodium falciparum gametogenesis essential protein 1 (GEP1) is a transmission‐blocking target

open access: yesFEBS Letters, EarlyView.
This study shows Plasmodium falciparum GEP1 is vital for activating sexual stages of malarial parasites even independently of a mosquito factor. Knockout parasites completely fail gamete formation even when a phosphodiesterase inhibitor is added. Two single‐nucleotide polymorphisms (V241L and S263P) are found in 12%–20% of field samples.

Rejuvenation of human mesenchymal stem cells using a nonintegrative and conditionally removable Sendai virus vector

open access: yesScientific Reports
Human mesenchymal stem cells (hMSCs) with extended lifespan and differentiation potential that can recapitulate in vivo characteristics could significantly contribute to basic research, drug development, and cell therapy.
