A molecular model of the assembled COPI coat, determined by cryo-electron tomography of an in vitro reconstituted budding reaction, reveals details of interactions mediating coat assembly and shows the binding site of ArfGAP2.
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 structure of the complete, membrane bound, COPII coat solved by sub-tomogram averaging reveals the arrangement of all protein subunits on the membrane and suggests a mechanism for coating heterogeneously-shaped carriers.
Parallel measurements of pH gradient and membrane potential at the single vesicle level have revealed that the synaptic vesicle acidification is initiated by removal of its clathrin coat, which blocks vesicular ATPase activity.
In isogenically matched colorectal cancer (CRC) cell lines, mutant KRAS alters the composition of secreted miRNAs in extracellular vesicles that can then transfer repressive activity to wild type cells.
The 24 ankyrin repeats of ankyrin proteins form an extended solenoid that provides an extremely conserved groove for binding to numerous targets via combinatorial usage of multiple weak interaction sites.
