Scaffolding proteins serve as sites of binding and organization for the multiple components involved in many signaling pathways. Scaffolding promotes key protein-protein interactions and can substantially amplify a signal; however, if proteins are bound too tightly to a scaffold, signal propagation may actually be hindered. The precise mechanisms that regulate… Read More

by Leigh MacMillan A team of Vanderbilt investigators has pinpointed the role of bile acids and a specific signaling pathway in the positive metabolic effects of weight-loss surgery. The findings, reported in the journal Gastroenterology, also suggest that the intestinal microbiome participates in post-surgery improvements. The results… Read More

Exocytic vesicles fuse with the plasma membrane (PM) through the action of SNARE proteins, which in turn, are delivered to the vesicles by multisubunit protein tethering complexes. One such complex is the exocyst, comprising two tetrameric subcomplexes, SC1 (composed of SEC3, SEC5, SEC6, and SEC8) and SC2 (composed of SEC10,… Read More
