mGluR2
Metabotropic glutamate receptor 2 (mGluR2) is a protein that, in humans, is encoded by the ''GRM2'' gene. mGluR2 is a G protein-coupled receptor (GPCR) that couples with the Gi alpha subunit. The receptor functions as an autoreceptor for glutam ...

LY-379,268 is a drug that is used in neuroscience research, which acts as a potent and selective agonist for the group II metabotropic glutamate receptors ( mGluR2/3).
It is derived from the older mGluR group II agonist eglumegad, and led on to ...
