This study identifies Impβ as a regulator of actin polymerization, showing its role in stress fiber formation and cell migration independent of nuclear transport.

The paper uses Alphafold3 to predict and validate the structure of the Imp{beta}/Imp7/H1 complex, showing H1 binds to Imp7 rather than Imp{beta} and identifying key interaction regions.

The paper introduces chemical crosslinking with mass spectrometry and a new search engine, NuXL, to identify nucleic acid-protein crosslinks at amino acid resolution, enhancing structural analysis.

The paper shows that VeA, a fungal transcription factor, shuttles between the cytoplasm and nucleus during different developmental stages, with nuclear localization required for sexual development and cytoplasmic presence needed for asexual development.

This study identifies transporters and a selectivity determinant in Leu-tRNA synthetase in Bacillus subtilis, revealing how photo-leucine is managed and its incorporation is limited to maintain cellular tolerance.
