Variability in G-Protein-Coupled Signaling Studied with Microfluidic Devices

G-protein Coupled Receptor Dimerization

A growing body of evidence suggests that GPCRs exist and function as dimers or higher oligomers. The evidence for GPCR dimerization comes from biochemical, biophysical and functional studies. In addition, researchers have shown the occurrence of heterodimerization between different members of the GPCR family. Two receptors can interact with each other to make a dimer through their extracellular...

G-protein-coupled signaling in Arabidopsis.

With an essentially complete plant genome in hand, it is now possible to conclude that a single or possibly just two canonical heterotrimeric G-protein complexes are present in Arabidopsis. In stark contrast, more than one hundred such complexes are found in some metazoans. Nonetheless, it appears that heterotrimeric G-protein complexes couple or affect many different signaling pathways in plan...

Heterotrimeric G protein-coupled signaling in plants.

Investigators studying G protein-coupled signaling--often called the best-understood pathway in the world owing to intense research in medical fields--have adopted plants as a new model to explore the plasticity and evolution of G signaling. Much research on plant G signaling has not disappointed. Although plant cells have most of the core elements found in animal G signaling, differences in ne...
