  Domain Name: PA_GCPII_like
PA_GCPII_like: Protease-associated domain containing protein, glutamate carboxypeptidase II (GCPII)-like. This group contains various PA domain-containing proteins similar to GCPII including, GCPIII (NAALADase2) and NAALADase L. These proteins belong to the peptidase M28 family. GCPII is also known N-acetylated-alpha-linked acidic dipeptidase (NAALDase1), folate hydrolase or prostate-specific membrane antigen (PSMA). GCPII is found in various human tissues including prostate, small intestine, and the central nervous system. In the brain, GCPII is known as NAALDase1, it functions as a NAALDase hydrolyzing the neuropeptide N-acetyl-L-aspartyl-L-glutamate (alpha-NAAG), to release free glutamate. In the small intestine, GCPII releases the terminal glutamate from poly-gamma-glutamated folates. GCPII (PSMA) is a useful cancer marker; its expression is markedly increased in prostate cancer and in tumor-associated neovasculature. GCPIII hydrolyzes alpha-NAAG with a lower efficiency than does GCPII; NAALADase L is not able to hydrolyze alpha-NAAG. The GCPII PA domain (referred to as the apical domain) participates in substrate binding and may act as a protein-protein interaction domain.
No pairwise interactions are available for this conserved domain.

Tips:
 If you've navigated here from a protein, hovering over a position on the weblogo will display the corresponding protein position for that domain position.

 The histograms below the weblogo indicate mutations found on the domain. Red is for disease (OMIM) and blue is for SNPs.

 Functional Features are displayed as orange boxes under the histograms. You can choose which features are displayed in the box below.
