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