This study identifies ELAVL family proteins as essential, evolutionarily conserved co-regulators that physically interact with Musashi (MSI) proteins to enable MSI-dependent translational activation of specific mRNAs during processes such as oocyte maturation and pituitary development.
This study reveals that Gβγ acts as a critical positive allosteric modulator that binds multiple sites on PLCβ3 to reorient its catalytic domain and facilitate maximal activation by Gq at the plasma membrane, rather than recruiting the enzyme to the membrane itself.
This study reveals that *Trypanosoma brucei* utilizes three distinct Oxa1 paralogs with specialized roles in mitochondrial membrane protein insertion, where TbOxa1-1 and TbOxa1-2 are essential for the biogenesis of specific oxidative phosphorylation complexes and TbOxa1-3 plays a minor role, demonstrating an evolutionary division of labor to manage a divergent mitochondrial proteome.
This study demonstrates that the carbon kinetic isotope effects of both Form I and Form II Rubisco enzymes decrease linearly with increasing temperature, challenging the long-held assumption that these values are temperature-independent and suggesting significant implications for interpreting carbon isotope records in Earth and biological sciences.
The paper introduces TripleToolWF, a workflow that combines outputs from three search engines to significantly increase the identification and quantification of high-confidence immunopeptides, thereby enabling a deeper analysis of the immunopeptidome for improved vaccine candidate prioritization.
This paper presents a genetic code expansion strategy for the site-specific incorporation of a switchable acridonylalanine-methyltetrazinyl phenylalanine fluorophore-quencher pair into proteins, enabling label-free monitoring of protein dynamics and high-throughput drug screening in systems like calmodulin, RecA, and LexA.
This study reveals that *Bacillus subtilis* and other Gram-positive bacteria overcome respiratory surface-area limitations by assembling Ndh and Ncp proteins with phospholipids into quinone-transporting filaments that create a continuous hydrophobic conduit for electron transfer, representing a third evolutionary strategy for cellular complexity distinct from the membrane invaginations of Gram-negatives and organelles of eukaryotes.
This study reveals that the structural diversity and stability of *E. coli* inclusion bodies are dictated by the native properties of the aggregating proteins, ranging from well-structured, native-like assemblies in stable globular proteins to heterogeneous, sequence-driven aggregates in disordered domains that partially recapitulate pathological fibril cores.
This study characterizes a hyperthermophilic Family B DNA polymerase from *Pyrolobus fumarii* A1, demonstrating its exceptional thermostability, high fidelity, broad pH tolerance, and inhibitor resistance, which collectively highlight its significant potential as a robust tool for molecular biology applications.
This study reveals that octopuses evolved a unique structural break in their core ribosomal RNA, which enhances translation fidelity to maintain proteomic stability amidst extensive RNA editing, thereby supporting the development of their complex nervous systems.
