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.
