Abstract
RNA binding proteins (RBPs) are key regulators of controlling the proteome remodeling during T-cell activation. Using proximity labeling, we present a comprehensive interactome map of the RBP ZFP36L1, demonstrating the versatility of interactions and their possible functioning during T-cell activation.
ORF1p, a LINE-1-encoded protein, regulates chromatin accessibility, neuron-specific gene expression, and neurite morphology in post-mitotic neurons, revealing a physiological role for this retrotransposon protein in the brain.

PUM2 expression increases upon aging and this facilitates the capture/trapping of Mff mRNA, either alone or in association with other RNA-binding proteins (RBPs) in Ribonucleoprotein particles (RNP).
Discovered in the 1970s, nuclear lamins control chromatin organization and are linked to many diseases. Zhang et al. now find that lamin A/C quantitatively constrains DNA replication initiation by limiting chromatin accessibility and sequestering PCNA, extending lamin’s long-known role in replication to the control of...

Cohesin organizes genome folding through loop extrusion, a process regulated by cofactors including NIPBL and PDS5. Recent studies by Wutz et al. and Shah et al. demonstrate that NIPBL promotes loop expansion in mammalian cells, whereas PDS5 restricts loop growth by facilitating NIPBL dissociation from cohesin. Togethe...

This work identifies circFut8—a conserved exonic circRNA originating from FUT8 gene exon 3—as a bc tumor suppressor, which is significantly downregulated in bc tissues and cell lines, correlating with advanced tumor grade and invasion.

Ji and colleagues show that endothelial deletion of PCBP1, a multifunctional nucleic-acid-binding protein, reduces intra-arterial hematopoietic cluster formation and impairs subsequent hematopoietic development. These findings identify PCBP1 as a new regulator of early definitive hematopoiesis while leaving its underly...
