Cooperative association of a histone-binding complex with pairs of appropriately modified nucleosomes, which form fundamental units of binding, mediates selective heterochromatin assembly and spreading.

A conserved element in the flavivirus genomic 5′ terminus switches its conformation in response to long-range RNA interactions, and thereby regulates the dynamic recruitment of viral replicase for efficient viral RNA replication.

NusG enhances transcription elongation by stabilizing DNA base pairs immediately upstream of the RNA-DNA hybrid but does not measurably affect the nucleotide incorporation and the forward translocation by RNA polymerase.

The ATPase Dhh1 controls processing body formation and disassembly in yeast cells, and processing body dynamics can be recapitulated in vitro with recombinant Dhh1, ATP and RNA.

HID-1 is a novel player mediating homotypic fusion of immature secretory granules.

Multiple roles of the auxiliary calcium channel α2δ subunits require proteolytic cleavage of the precursor protein into α2 and δ.

Building on previous work (Pless, 2013), we argue that side-chain 'flip out' is a key event in potassium channel C-type inactivation, and propose a new method for encoding multiple noncanonical amino acids and controlling protein stoichiometry.

Novel post-translational modification of pattern recognition receptor TLR2 has consequences in bacterial infection and inflammatory signaling.

Ankyrin-B – through interactions with PI3P lipids, dynactin and RabGAP1L – functions as a critical node in the protein circuitry underlying polarized recycling of α5β1-integrin to enable haptotaxis along fibronectin gradients.

The crystal structure of the trans-activation response region (TAR) bound to HIV-1 Tat and an elongation factor, together with HDX, SHAPE, SAXS, and integrative modeling, shows how TAR binds this complex in two ways.
