The mechanism by which the polycationic neomycin enters specific eukaryotic cell types remains poorly understood. In budding yeast, <i>NEO1</i> is required for neomycin resistance and encodes a phospholipid flippase that establishes membrane asymmetry. Here we show that mutations altering Neo1 substrate recognition cause neomycin hypersensitivity by exposing phosphatidylinositol-4-phosphate (PI4P) in the plasma membrane extracellular leaflet. Cryogenic electron microscopy reveals PI4P binding to Neo1 within the substrate translocation pathway. PI4P enters the lumen of the endoplasmic reticulum and is flipped by Neo1 at the Golgi to prevent PI4P secretion to the cell surface. Deficiency of the orthologous ATP9A in human cells also causes exposure of PI4P and neomycin sensitivity. These findings unveil conserved mechanisms of aminoglycoside sensitivity and phosphoinositide homoeostasis, with important implications for signalling by extracellular phosphoinositides.</p>","PeriodicalId":18977,"journal":{"name":"Nature Cell Biology","volume":"22 1","pages":""},"PeriodicalIF":21.3,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144603106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Analyses of diverse factor combinations highlight its versatility and superior resolution. By tracking lamina-associated domain inheritance over the cell cycle, we showcase that Dam&ChIC provides retrospective single-cell chromatin data. When applied in random X chromosome inactivation, Dam&ChIC disentangles the temporal order of chromatin remodelling events.

Here we show that BLTP2 regulates plasma membrane (PM) fluidity by increasing phosphatidylethanolamine (PE) levels in the PM. BLTP2 localizes to endoplasmic reticulum (ER)–PM contact sites, and transports PE in vivo, suggesting it drives PE movement from ER to PM. We find that BLTP2 works in parallel with another pathway that regulates intracellular PE distribution and PM fluidity. BLTP2 expression correlates with breast cancer aggressiveness.

When autophagy is inhibited, the autophagy cargo receptors NBR1 and p62/SQSTM1 accumulate within biomolecular condensates in cells, which drives basal differentiation in both mouse and human breast cancer models. Mechanistically, these NBR1–p62/SQSTM1 complexes sequester ITCH, a ubiquitin ligase that degrades and negatively regulates p63 in breast cancer cells, thereby stabilizing and activating p63. Accordingly, mutant forms of NBR1 unable to sequester ITCH into NBR1–p62/SQSTM1 complexes do not promote basal differentiation and metastasis in vivo.
