What is N-acetyl aspartyl-glutaMic acid?

Chemical properties

White powder

The Uses of N-acetyl aspartyl-glutaMic acid

N-acetyl aspartyl-glutamic acid is a spaglumic acid is a marker of neuronal integrity and was used in the detection of therapeutic values of antidrepressant treatments.

The Uses of N-acetyl aspartyl-glutaMic acid

N-Acetyl-Asp-Glu has been used in N-acetylated α-linked acidic dipeptidase (NAALADase) assay and affinity experiments.

What are the applications of Application

N-Acetyl-Asp-Glu-OH is an endogenous neurotransmitter with high affinity for mGluR-3

Definition

ChEBI: A dipeptide composed of N-acetyl-L-aspartic acid and L-glutamic acid joined by a peptide linkage.

General Description

NAAG is a neuropeptide and a neurotransmitter that is abundant in the mammalian nervous system. It remains uncertain whether this compound activates NMDA receptors; however, it is clearly demonstrated to act as a selective agonist of mGluR3, both in vitro and in vivo.

Biochem/physiol Actions

Endogenous neurotransmitter localized to neurons with high affinity for metabotropic glutamate receptors, mGluR3. It is an antagonist at NMDA receptors. Catabolized by carboxypeptidase II, which is expressed on astrocyte membranes, to N-acetylaspartate and glutamate.
