Structural and functional analyses show how the spliceosomal Prp3 protein concomitantly binds double- and single- stranded regions in U4/U6 di-snRNAs and serves to stabilize the U4/U6•U5 tri-snRNP for splicing.
Single-cell RNA sequencing of Drosophila hemocytes in blood distinguishes various states within known blood cell types and implicates a novel role for fibroblast growth factor receptor signaling in inter-hemocyte crosstalk.
Integrative structural biology reveals a conformational equilibrium in the Box C/D methylation enzyme that regulates the extent of site-specific 2'-O-rRNA methylation in dependence of the RNA sequence.
Hinokiflavone is identified as a splicing modulator that blocks progression from spliceosome complex A to complex B and inhibits SUMO protease SENP1, causing hyper-SUMOylation affecting 6 U2 snRNP proteins.
The high-resolution structure of a filamentous flexible plant virus shows that there is structural homology between its coat protein and the nucleoproteins of an unrelated group of enveloped RNA animal viruses.
A geneome-scale shRNA screen identifies five genes whose suppression promotes cell death upon PI3K inhibition both in vitro and in vivo, thus suggesting potential combination therapies involving PI3K inhibition.
