    Live-cell mapping of organelle-associated RNAs via proximity biotinylation combined with protein-RNA crosslinking

    Pornchai Kaewsapsak et al.
    Live-cell nanometer-resolution RNA labeling method enables transcriptome-wide mapping of endogenous RNAs in nuclear, cytosol, ER, and mitochondrial subcompartments.

    Endocytic recycling and vesicular transport systems mediate transcytosis of Leptospira interrogans across cell monolayer

    Yang Li et al.
    L. interrogans utilizes endocytic recycling and vesicular transport systems for transcytosis across endothelial or epithelial barrier in blood vessels or renal tubules, which contributes to spreading and transmission of leptospirosis.

    SMC5/6 is required for replication fork stability and faithful chromosome segregation during neurogenesis

    Alisa Atkins et al.
    The structural maintenance of chromosomes complex, SMC5/6, is crucial for brain development and function as it ensures proficient DNA replication in neural progenitor cells prior to chromosome segregation.

    Torsin ATPases influence chromatin interaction of the Torsin regulator LAP1

    Naemi Luithle et al.
    The INM protein LAP1B, an activator of Torsin ATPases, is a chromatin-binding factor that erroneously persists on mitotic chromatin if Torsin functionality is compromised, inducing chromosome segregation defects and binucleation.

    Casein kinase 1G2 suppresses necroptosis-promoted testis aging by inhibiting receptor-interacting kinase 3

    Dianrong Li et al.
    Casein kinase 1G2 interacts with and inhibits the activation of receptor-interacting kinase 3, RIP3, in response to TNF and toll-like receptor family members and attenuates its necroptosis signaling activity.

    Coordinated crosstalk between microtubules and actin by a spectraplakin regulates lumen formation and branching

    Delia Ricolo, Sofia J Araujo
    Lumen formation by single epithelial cells depends on FGF-signalling-dependent expression of a spectraplakin, which can be functionally replaced by Tau.

    A conserved LDL-receptor motif regulates corin and CD320 membrane targeting in polarized renal epithelial cells

    Ce Zhang et al.
    A conserved motif in corin and CD320 LDL receptor modules regulates specific apical trafficking in polarized renal epithelial cells.

    Single-cell dynamics of pannexin-1-facilitated programmed ATP loss during apoptosis

    Hiromi Imamura et al.
    Cleavage of pannexin-1 channel by caspases facilitates the loss of intracellular ATP level and attenuates glycolytic metabolism of apoptotic cells.

    Genome-wide effects of the antimicrobial peptide apidaecin on translation termination in bacteria

    Kyle Mangano et al.
    Inhibition of bacterial protein synthesis by an antimicrobial peptide apidaecin triggers translation arrest at the stop codons, ribosome queuing and pervasive stop codon readthrough.

    Elongation inhibitors do not prevent the release of puromycylated nascent polypeptide chains from ribosomes

    Benjamin D Hobson et al.
    Although puromycin staining is often used to examine subcellular translation, puromycin-labeled proteins are rapidly released from ribosomes even in the presence of elongation inhibitors, which may confound translation site localization.
