Unstructured loop is essential for the activation of mGluR2.

Metabotropic Glutamate Receptors (mGluRs) are Class C G-protein coupled receptors (GPCRs) that are expressed throughout the central nervous system and are involved in several neurological and psychiatric disorders. Although, many studies focused on Glutamate induced activation of mGluR2, however, the role of unstructured loop (or "BC loop") in activation of metabotropic Glutamate receptors is currently unknown. Here, using Förster Resonance Energy Transfer (FRET) based assay in live cells we show that unstructured loop is required for Glutamate induced conformation and hence the activation of the receptor.
