“…In Schizosaccharomyces pombe, loss of the plasma membrane PI4-kinase scaffold Efr3 leads to sliding of the cytokinetic ring (CR) away from the cell center during anaphase, implicating phosphoinositides (PIPs) in CR anchoring. …”

“…In this study, we identify Rga3, a paralog of Rga4, as a novel Cdc42 GTPase-activating protein (GAP) in the fission yeast Schizosaccharomyces pombe. Contrary to Rga4, Rga3 localizes with Cdc42-GTP to sites of polarity. …”

“…We further show that despite the generally accepted view, a similar scaling phenomenon can occur in the sister species, Schizosaccharomyces pombe. Our results demonstrate that scaling is required for normal cell function and delineate possible rules for cellular geometry maintenance in populations of proliferating cells.…”

“…Q34 modification stimulates Dnmt2/Pmt1-dependent C38 methylation (m(5)C38) in the tRNA(Asp) anticodon loop in Schizosaccharomyces pombe. Here, we show by ribosome profiling in S. pombe that Q modification enhances the translational speed of the C-ending codons for aspartate (GAC) and histidine (CAC) and reduces that of U-ending codons for asparagine (AAU) and tyrosine (UAU), thus equilibrating the genome-wide translation of synonymous Q codons. …”

“…Here, we explore a conserved role for mitochondria in dynein anchoring by examining the tethering functions of the evolutionarily distant Schizosaccharomyces pombe Num1 homologue. In addition to its function in dynein anchoring, we find that S. pombe Num1, also known as Mcp5, interacts with and tethers mitochondria to the plasma membrane in S. pombe and Saccharomyces cerevisiae. …”

“…Many eukaryotic cells divide using a contractile apparatus called the cytokinetic ring (CR) that associates dynamically with the plasma membrane (PM) and generates force that contributes to PM ingression between daughter cells. In Schizosaccharomyces pombe, important membrane–CR scaffolds include the paralogous F-BAR proteins Cdc15 and Imp2. …”

“…Instead, RNA processing at transcriptional termination appears to define condensin accumulation sites during mitosis, in the fission yeast Schizosaccharomyces pombe. Combining the auxin-degron strain with the nda3 β-tubulin cold-sensitive (cs) mutant enabled us to inactivate condensin in mitotically arrested cells, without releasing the cells into anaphase. …”
