General description
GRIN2B (glutamate ionotropic receptor NMDA type subunit 2B) codes for N-methyl d-aspartate receptor subtype 2B (GluN2B). It belongs to the N-methyl-D-aspartate receptor (NMDAR) gene family. It is located on chromosome 12p13.1.
Application
6-Methyl-2-(phenylethynyl)pyridine hydrochloride has been used to investigate whether 3, 4 (±) methylenedioxymethamphetamine (MDMA) could influence self-renewal via the mGlu5 receptor in mouse embryonic stem cells (mESCs).
Biochem/physiol Actions
GRIN2B (glutamate ionotropic receptor NMDA type subunit 2B) plays an important role in the growth of neurons and is highly essential for learning and memory. GRIN2B mutation is associated with neuropsychiatric and developmental disorders like schizophrenia, Parkinson′s disease and bipolar disorder. MPEP (2-methyl-6-(phenylethynyl)pyridine hydrochloride) is used to treat Alzheimer′s disease (AD).
Highly selective, non-competitive mGluR5 metabotropic glutamate receptor antagonist.

In the present paper we describe 2-methyl-6-(phenylethynyl)-pyridine (MPEP) as a potent, selective and systemically active antagonist for the metabotropic glutamate receptor subtype 5 (mGlu5). At the human mGlu5a receptor expressed in recombinant cells, MPEP completely inhibited quisqualate-stimulated phosphoinositide (PI) hydrolysis
