A cell-free system combined with cell-based assays elucidate the biochemical mechanism of signal transduction mediated by the mitochondrial protein MAVS and delineates the role of ubiquitin E3 ligases in antiviral innate immune responses.

Long and short variants of a protein called UNC-13, assisted by another called Tomosyn, regulate the timing of synaptic vesicle release in C. elegans.

A cell-free biochemical assay for protein lipidation identifies the ER–Golgi intermediate compartment as a key early station in the formation of an autophagosome.

Membrane receptor proteins move through primary cilia largely by passive diffusion rather than by active intraflagellar transport.

Hundreds of cell growth and stress response genes are controlled by a rare small RNA component of an ancient splicing machinery, providing a raison d'être for its previously unexplained evolutionary conservation.

The recycling of transmitter vesicles at synapses shows calcium-dependent regulation that depends on the phosphorylation status of an enzyme called dynamin.

Physical contact between two Myxococcus xanthus cells is sufficient to fuse their outer membrane transiently and exchange outer membrane proteins and lipids at high efficiency.

Parallel branches of the ERAD pathway regulate sterol synthesis at multiple steps via feedback inhibition.

α-SNAP mediated rearrangement of Stim1 and Orai1 molecules within CRAC channel clusters is required for store-operated calcium entry.
