Beschreibung

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.[1][2]. It has also been used as a metabolite standard in liquid chromatography-mass spectrometry (LC-MS) targeted metabolomics analysis[3] and mass-spectroscopy-based stable isotope-resolved metabolomics (SIRM) with 13C515N2-labeled-glutamine.[4]

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.

Endogenous neurotransmitter localized to neurons with high affinity for metabotropic glutamate receptors, mGluR₃; NMDA receptor antagonist.

N-Acetyl-Asp-Glu (NAAG) is an abundant neuropeptide and neurotransmitter found in the mammalian brain.[5] NAAG acts as an agonist for metabotropic glutamate receptors, mGluR3.[3] In addition, it also acts as an antagonist for the N-methyl d-aspartate (NMDA) receptors.[5] 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.[3]
