    Time-resolved RNA–protein cross-linking with a pulsed femtosecond ultraviolet laser, followed by immunoprecipitation and high-throughput sequencing, enables the determination of binding and dissociation kinetics of the RNA-binding protein DAZL within cells.

    A protein condensate formed by multivalent interactions between the long non-coding RNA Xist and specific RNA-binding proteins drives the compartmentalization required to perpetuate gene silencing on the inactive X chromosome.

    Structures of prokaryotic homologues of STING permit the reconstruction of the evolutionary trajectory of its incorporation into metazoan innate immunity, and reveal a role for the conserved cGAS–STING pathway in prokaryotic defence against bacteriophages.

    The assembly of single Drosophila RNA-induced silencing complexes (RISCs) is reconstituted using seven purified proteins, revealing that chaperones help stabilize the interaction of the protein heterodimer Dicer-2–R2D2 bound to the short interfering RNA with Ago2.

    The crystal structure of the RNA binding domains of Sxl and Unr with msl2 RNA shows that interwoven interactions establish cooperative assembly of the ternary complex, highlighting how binding of relatively general RNA binding domains to RNA can result in a unique and specific protein–RNA architecture.

    The RNA-binding protein FMR1 has a key role in the neurodevelopmental disorder fragile X syndrome, but the RNAs targeted by the protein were mostly unknown. An analysis reveals thousands of possible targets. See Article p.382

    RNA-recognition elements are identified for the fragile-X-syndrome-associated RNA-binding protein FMRP, in addition to its target messenger RNAs; although many of FMRP gene targets discovered are involved in brain function and autism spectrum disorder, a proportion are also dysregulated in mouse ovaries, suggesting cross-regulation of signalling pathways in different tissues.

    A complex of RNA and protein known as the box C/D RNP catalyses the site-specific modification of RNAs with a 2′-O-methylation group. The structure of the full complex has now been solved, including the guide RNA and either of two substrate RNAs. This structure reveals how the guide and target RNAs are aligned, and how the methyltransferase subunit, fibrillarin, facilitates placement of the target ribose into the active site.

    Splicing is carried out by a collection of protein–RNA complexes known as snRNPs. The spliceosome contains equal quantities of the U1, U2, U4, U5 and U6 snRNPs, but the U1 snRNP is made in levels excess to the amounts needed to form spliceosomes, leading to the idea that excess U1s might have splicing independent functions. Here it is shown that the U1 snRNA interacts with some pre mRNAs whose introns have cryptic polyadenylation sites. This interaction prevents premature termination and polyadenylation of the pre mRNA.

    The association of microRNAs with Argonaute proteins (AGOs) yields complexes regulating gene expression. Although bacterial and archaeal miRNAs show no sequence preference at their 5′ ends, eukaryotic miRNAs tend to have a 5′ U or A. Here the structure of the human AGO2 MID domain complexed with ribonucleotide monophosphates is solved, revealing specific interaction of UMP and AMP with a loop that discriminates against CMP or GMP, and explaining the observed preference.
