  Domain Name: PBP1_mGluR
Ligand binding domain of the metabotropic glutamate receptors (mGluR). Ligand binding domain of the metabotropic glutamate receptors (mGluR), which are members of the family C of G-protein-coupled receptors that transduce extracellular signals into G-protein activation and ultimately into cellular responses. mGluRs bind to glutamate and function as an excitatory neurotransmitter; they are involved in learning, memory, anxiety, and the perception of pain. Eight subtypes of mGluRs have been cloned so far, and are classified into three groups according to their sequence similarities, transduction mechanisms, and pharmacological profiles. Group I is composed of mGlu1R and mGlu5R that both stimulate PLC hydrolysis. Group II includes mGlu2R and mGlu3R, which inhibit adenylyl cyclase, as do mGlu4R, mGlu6R, mGlu7R, and mGlu8R, which form group III.
No pairwise interactions are available for this conserved domain.

Tips:
 If you've navigated here from a protein, hovering over a position on the weblogo will display the corresponding protein position for that domain position.

 The histograms below the weblogo indicate mutations found on the domain. Red is for disease (OMIM) and blue is for SNPs.

 Functional Features are displayed as orange boxes under the histograms. You can choose which features are displayed in the box below.
