Description

Amino Acid Sequence

NAc-Asp-Glu

General description

Research area: Neuroscience

Application

N-Acetyl-Asp-Glu has been used in N-acetylated α-linked acidic dipeptidase (NAALADase) assay and affinity experiments.. It has also been used as a metabolite standard in liquid chromatography-mass spectrometry (LC-MS) targeted metabolomics analysis and mass-spectroscopy-based stable isotope-resolved metabolomics (SIRM) with 13C515N2-labeled-glutamine.

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.

N-Acetyl-Asp-Glu (NAAG) is an abundant neuropeptide and neurotransmitter found in the mammalian brain. NAAG acts as an agonist for metabotropic glutamate receptors, mGluR3. In addition, it also acts as an antagonist for the N-methyl d-aspartate (NMDA) receptors. It yields N-acetyl aspartate and glutamate through glutamate carboxypeptidase II (GCP II) dependent pathway. Thus, it serves as a key glutamate reservoir in cancer cells. NAAG levels in plasma could be used as a non-invasive biomarker for tumor progression.
