Citation | Journal: bioRxiv / Year: 2023 Title: Step-wise activation of a Family C GPCR. Authors: Kaavya Krishna Kumar / Haoqing Wang / Chris Habrian / Naomi R Latorraca / Jun Xu / Evan S O'Brien / Chensong Zhang / Elizabeth Montabana / Antoine Koehl / Susan Marqusee / Ehud Y Isacoff / Brian K Kobilka / ![]() Abstract: Metabotropic glutamate receptors belong to a family of G protein-coupled receptors that are obligate dimers and possess a large extracellular ligand-binding domain (ECD) that is linked via a cysteine- ...Metabotropic glutamate receptors belong to a family of G protein-coupled receptors that are obligate dimers and possess a large extracellular ligand-binding domain (ECD) that is linked via a cysteine-rich domain (CRDs) to their 7-transmembrane (TM) domain. Upon activation, these receptors undergo a large conformational change to transmit the ligand binding signal from the ECD to the G protein-coupling TM. In this manuscript, we propose a model for a sequential, multistep activation mechanism of metabotropic glutamate receptor subtype 5. We present a series of structures in lipid nanodiscs, from inactive to fully active, including agonist-bound intermediate states. Further, using bulk and single-molecule fluorescence imaging we reveal distinct receptor conformations upon allosteric modulator and G protein binding. | |||||||||
