Hydrolysis of the neuropeptide N-acetyl-L-aspartyl-L-glutamate (NAAG) by N-acetylated α-linked acidic dipeptidase (NAALADase) to release glutamate may be important in a number of neurodegenerative disorders in which excitotoxic mechanisms are implicated. NAALADL1 (N-acetylated α-linked acidic dipeptidase-like 1), also known as I100 or NAALADASEL, is a 740 amino acid single-pass type II membrane protein. Belonging to the peptidase M28 family and the M28B subfamily, NAALADL1 is mainly expressed in the distal small intestine, spleen and testis. It is also weakly expression in the brain, locating mainly to the brain stem, amygdala, thalamus and ventral striatum. NAALADL1 is considered a novel ileal brush border membrane protein.
