Schizosaccharomyces pombe Minichromosome Maintenance-binding Protein (MCM-BP) Antagonizes MCM Helicase [PDF]

Journal of Biological Chemistry, 2011
The minichromosome maintenance (MCM) complex, a replicative helicase, is a heterohexamer essential for DNA duplication and genome stability. We identified Schizosaccharomyces pombe mcb1(+) (Mcm-binding protein 1), an apparent orthologue of the human MCM-binding protein that associates with a subset of MCM complex proteins. mcb1(+) is an essential gene.

Ramalin Ameliorates Alzheimer's Disease Pathology by Targeting BACE1, HDAC6, and MAPK Pathways

MedComm, Volume 7, Issue 1, January 2026.
Ramalin alleviates Alzheimer's disease pathology by selectively inhibiting HDAC6, reducing BACE1 levels, and suppressing neuroinflammation through downregulation of the NLRP3 inflammasome and iNOS. It restores synaptic function impaired by Aβ toxicity and improves cognitive performance in AD mouse models, APP/PS1 and 3xTg‐AD.

Checkpoint-Dependent Regulation of Origin Firing and Replication Fork Movement in Response to DNA Damage in Fission Yeast [PDF]

, 2009
To elucidate the checkpoint mechanism responsible for slowing passage through S phase when fission yeast cells are treated with the DNA-damaging agent methyl methanesulfonate (MMS), we carried out two-dimensional gel analyses of replication intermediates

New vectors for epitope tagging and gene disruption in Schizosaccharomyces pombe

BioTechniques, 2013
We describe a series of new vectors for PCR-based epitope tagging and gene disruption in the fission yeast Schizosaccharomyces pombe, an exceptional model organism for the study of cellular processes.

Update of the list of qualified presumption of safety (QPS) recommended microbiological agents intentionally added to food or feed as notified to EFSA 23: Suitability of taxonomic units notified to EFSA until September 2025

EFSA Journal, Volume 24, Issue 1, January 2026.
Abstract The qualified presumption of safety (QPS) process was developed to provide a harmonised safety assessment approach to support EFSA Scientific Panels and Units. The QPS approach assesses the taxonomic identity, body of relevant knowledge and safety of microorganisms intentionally added to the food and feed chain.

The RNA Binding Protein Csx1 Promotes Sexual Differentiation in Schizosaccharomyces pombe

PLoS ONE, 2012
Sexual differentiation is a highly regulated process in the fission yeast Schizosaccharomyces pombe and is triggered by nutrient depletion, mainly nitrogen source. One of the key regulatory proteins in fission yeast sexual differentiation is the transcription factor Ste11.

Rad27/FEN1 prevents accumulation of Okazaki fragments and ribosomal DNA copy number changes

FEBS Letters, Volume 599, Issue 24, Page 3669-3684, December 2025.
The budding yeast Rad27 is a structure‐specific endonuclease. Here, the authors reveal that Rad27 is crucial for maintaining the stability of the ribosomal RNA gene (rDNA) region. Rad27 deficiency leads to the accumulation of Okazaki fragments and changes in rDNA copy number.

Regulation of Ace2-dependent genes requires components of the PBF complex in schizosaccharomyces pombe [PDF]

, 2015
The division cycle of unicellular yeasts is completed with the activation of a cell separation program that results in the dissolution of the septum assembled during cytokinesis between the 2 daughter cells, allowing them to become independent entities ...

Coming to Terms: The Mechanisms of Overplus and Luxury Phosphorus Uptake for Polyphosphate Storage in Microalgae and Yeast

Biotechnology and Bioengineering, Volume 122, Issue 12, Page 3486-3495, December 2025.
Plouviez et al. give a perspective on the terminology used for describing the mechanisms of polyphosphate accumulation in microalgae and yeast. Their differentiation of mechanisms is based on environmental P availability, polyP chemistry, genetics, or cellular function as described in recent literature.
