Rqc2-mediated modification of ribosome-stalled nascent chains with "CAT tails" promotes formation of insoluble aggregates suggesting that proteins can become specifically marked for aggregation.

The regulation of the core transcription factor Oct4 by the Aurkb-PP1 axis links the cell cycle to pluripotency programs in embryonic stem cells.

An ancient complex comprising the eukaryotic elongation factor-1A and aminoacylated tRNA is shown to be the target of a cyclic heptapeptide and two unrelated natural products with potent anticancer activity.

Inhibiting PRMT1 enzymatic activity promotes megakaryocyte terminal differentiation via RBM15-mediated RNA metabolism, which is dysregulated in hematological malignancies.

A systems level reconstitution of H-Ras GTPase signaling reveals a rich space of tunable dynamic outputs and clarifies the consequences of oncogenic perturbations to signaling.

Lipidated and highly hydrophobic Wnt ligands form a complex with the serum glycoprotein afamin, and can be purified and stored in a biologically active form without detergents.

Heat-induced local unfolding allows Hsf1 to form trimers and bind to DNA, which depends on Hsf1 concentration and is promoted, not inhibited, by Hsp90.

Single molecule FRET reveals that the SWI/SNF-family remodeling enzyme RSC translocates nucleosomes along the DNA in steps of ~1-2 base pairs in size.

Neuronal ELAV-like (nELAVL) proteins are associated with non-coding Y RNAs in stressed neurons and in the brains of Alzheimer's disease patients, suggesting a new means of regulatory protein sequestration and mRNA target regulation.

The I_Ks potassium channel complex displays functional flexibility that depends on the ratio of its constituent KCNQ1 and KCNE1 protein subunits.
