This study investigates the antifungal mechanism of cymoxanil, finding it disrupts plasma membrane potential and inhibits proton pumps in yeast, suggesting a mode of action involving membrane transport and acidification.

A stable microtubule bundle formed through an orchestrated multistep process controls quiescence exit

The paper describes the molecular mechanism of microtubule bundle assembly and disassembly during quiescence exit in yeast.

A new technology for isolating organellar membranes provides fingerprints of lipid bilayer stress

The paper introduces a method to isolate organellar membranes from yeast and uses it to study lipid composition and stress responses in the endoplasmic reticulum and vacuolar membranes.

Dually targeted proteins regulate proximity between peroxisomes and partner organelles

The paper investigates dually targeted proteins in yeast and shows they act as dynamic tethers between peroxisomes and partner organelles, contributing to their proximity and communication.

ER translocation of suboptimal targeting sequences depends on Sec61β/Sbh1 and its phosphorylation

The paper shows that phosphorylation of Sbh1 regulates ER translocation of proteins with suboptimal targeting sequences by inducing conformational changes.

A systematic approach to study protein-substrate specificity enables the identification of Ssh1 substrate range

The paper introduces Cel-lctiv, a method to study PPIs in yeast, and demonstrates its use in identifying the unique substrate range of Ssh1.

Determining the targeting specificity of the selective peroxisomal targeting factor Pex9

The paper investigates the targeting specificity of Pex9 by analyzing PTS1 motifs and structural features, finding that hydrophobicity of the amino acid before the PTS1 tripeptide determines its binding specificity.

Regulation of major bacterial survival strategies by transcript sequestration in a membraneless organelle

The paper shows that TmaR-mediated liquid-liquid phase separation in E. coli regulates sugar metabolism and enables bacterial survival strategies like motility and biofilm formation.

Systematic multi-level analysis of an organelle proteome reveals new peroxisomal functions

The paper identifies new peroxisomal functions in yeast by expanding the organellar proteome and analyzing sub-organellar localization and metabolic roles.

The paper identifies Pex34p as a crucial factor for de novo peroxisome biogenesis in yeast, alongside Pex25p, through genetic screening and interaction studies.

Mitochondrial ribosomal proteins developed unconventional mitochondrial targeting signals due to structural constraints

The paper identifies internal mitochondrial targeting signals in yeast mitochondrial ribosomal proteins, showing that 30% of them use non-conventional signals not reliably predicted by existing methods.

Translational control as a novel regulator of gradient sensing and chemotropism in yeast

This study identifies translational control as a regulator of chemotropism in yeast by discovering genes involved in gradient sensing and mating.

The mitochondrial surface receptor Tom70 protects the cytosol against mitoprotein-induced stress

The paper identifies Tom70's role in recruiting cytosolic chaperones to the mitochondrial outer membrane to mitigate proteotoxicity from hydrophobic precursor proteins.

Pex14p phosphorylation modulates import of citrate synthase 2 into peroxisomes in Saccharomyces cerevisiae

This study shows that phosphorylation of Pex14p at serine 266 regulates the import of Cit2p into peroxisomes, affecting yeast metabolism under different carbon sources.

AMPK regulates ESCRT-dependent microautophagy of proteasomes concomitant with proteasome storage granule assembly during glucose starvation

The paper shows AMPK and ESCRTs drive microautophagy of proteasomes during glucose starvation, leading to proteasome storage granule assembly and functional proteasome retention.

Multiplexed electron microscopy by fluorescent barcoding allows screening for ultrastructural phenotype

The paper introduces a method using fluorescent barcoding and electron microscopy to enable high-throughput screening of ultrastructural phenotypes in yeast.

Transfer of Septin Rings to Cytokinetic Remnants Directs Age-Sensitive ER stress Surveillance Cell Cycle Re-entry

Non-Canonical Regulation of Phosphatidylserine Metabolism by a Phosphatidylinositol Transfer Protein and a Phosphatidylinositol 4-OH Kinase

The paper shows that Psd2-dependent phosphatidylethanomaine production in yeast relies on Psd2, Sfh4, and Stt4, with Sfh4 activating the pathway through a physical interaction rather than its PtdIns transfer activity.
