This study demonstrates that in mice, plasmanyl lipids are sufficient to prevent cataracts and maintain fertility, indicating that plasmalogens are dispensable for retinal integrity and reproductive function despite their critical role in total ether lipid deficiency.
This study presents the first proteome-wide analysis revealing that mammalian proteins, including transcription factors and DNA repair enzymes, exhibit diverse and symmetry-specific recognition patterns for 5-formylcytosine modifications in CpG dyads, thereby modulating target selection and chromatin regulation.
This study elucidates how TFAM-induced promoter bending creates a transcription-stimulatory interface between PolRMT and upstream DNA, while a PolRMT tether helix acts as an autoinhibitory element to ensure promoter specificity, thereby defining the structural mechanisms governing mitochondrial transcription regulation.
This study elucidates the structural mechanism of Gi-biased allosteric modulation in the GPR84 receptor by identifying a novel helix 8-proximate binding site for the positive allosteric modulator PSB-16671, which stabilizes a specific receptor conformation to enhance macrophage phagocytosis while avoiding desensitization.
This study identifies TCF25 as a predominantly cytoplasmic, membrane-associated protein that regulates the stability of GPRASP2, a relationship disrupted by the L415P variant, thereby establishing a new role for TCF25 in cellular proteostasis.
This study demonstrates that a urea-gradient nanoDSF approach overcomes the kinetic stability limitations of hyperthermophilic proteins, enabling reliable determination of their melting temperatures by inducing detectable unfolding transitions that are absent under native conditions.
This study demonstrates that machine learning models identify pH-dependent lipophilicity (logD) as the dominant factor governing small molecule partitioning into biomolecular condensates, establishing ionization-coupled partitioning as a key mechanistic driver of phase separation behavior.
This study comprehensively characterizes twelve ferredoxin isoforms in *Synechocystis* sp. PCC 6803 through spectroscopic, electrochemical, and expression analyses, revealing a diverse suite of proteins with varying redox potentials and regulatory patterns that collectively maintain cellular redox homeostasis by supporting both core photosynthetic electron transfer and specialized metabolic functions.
This study introduces a novel, rapid, and sensitive semi-quantitative HPLC-MS/MS method capable of detecting the widest range of isoprenoid quinones to date, successfully revealing stage-specific microbial community shifts in wastewater treatment samples.
This study reveals that dihydroxy-enone-type protein-bound ceramides, rather than the previously studied epoxy-enone types, are the predominant class in human stratum corneum and are likely generated via epoxide hydrolase EPHX3-mediated conversion, highlighting a fundamental structural difference between human and mouse skin barrier lipids.
