Ultraviolet crosslinking and immunoprecipitation (CLIP) methodologies enable the identification of RNA binding sites of RNA-binding proteins (RBPs). Despite improvements in the library preparation of RNA fragments, the enhanced CLIP (eCLIP) protocol requires 4 days of hands-on time and lacks the ability to process several RBPs in parallel. We present a new method termed antibody-barcode eCLIP that utilizes DNA-barcoded antibodies and proximity ligation of the DNA oligonucleotides to RBP-protected RNA fragments to interrogate several RBPs simultaneously. We observe performance comparable with that of eCLIP with the advantage of dramatically increased scaling while maintaining the same material requirement of a single eCLIP experiment.

Despite the widespread use of clinical anesthesia, the process of emergence from general anesthesia remains primarily driven by anesthetic elimination. Although emergence from general anesthesia is typically safe, prolonged delays strain resource-intensive settings and contribute to increased healthcare costs. In addition to improving access to care, providing clinicians with more precise control over emergence could offer diagnostic potential and improve patient outcomes.

Methylation of histone H3 at lysine 9 (H3K9me), a hallmark of heterochromatin, is catalyzed by Clr4/Suv39. Clr4/Suv39 contains two conserved domains-an N-terminal chromodomain and a C-terminal catalytic domain-connected by an intrinsically disordered region (IDR). Several mechanisms have been proposed to regulate Clr4/Suv39 activity, but how it is regulated under physiological conditions remains largely unknown.

BRCA2 is crucial for mediating homology-directed DNA repair (HDR) through its binding to single-stranded DNA (ssDNA) and the recombinases RAD51 and DMC1. Most BRCA2 orthologs have a canonical DNA-binding domain (DBD) with the exception of Drosophila melanogaster. It remains unclear whether such a noncanonical BRCA2 variant without DBD possesses a DNA-binding activity.

The CST (CTC1-STN1-TEN1) complex, a single-stranded DNA (ssDNA) binding complex, is essential for telomere maintenance and genome stability. Depletion of either CTC1 or STN1 results in cellular senescence, while mutations in these components are associated with severe hereditary disorders. In this study, we demonstrate that the direct STN1-CTC1 interaction stabilizes CTC1 by preventing its degradation via TRIM32 mediated ubiquitination.

Abscisic acid (ABA) and calcium respectively work as crucial plant hormones and second signalling molecules in the regulation of fruit development and quality formation, including the sugar content and flavour quality. However, the regulatory mechanisms of fruit sugar accumulation arising from the interaction between ABA and calcium have not yet been fully elucidated. Here, we show that the application of ABA or calcium enhances sugar accumulation in sweet orange (Citrus sinensis) fruit, accompanied by upregulation of the expression level of tonoplast sugar transporter 2 (CsTST2), which mediates the transport of sugars into the vacuole.
