  • 功能：
    Catalyzes the deacetylation of N-acetylaspartic acid (NAA) to produce acetate and L-aspartate. NAA occurs in high concentration in brain and its hydrolysis NAA plays a significant part in the maintenance of intact white matter. In other tissues it act as a scavenger of NAA from body fluids.

    1. report of 2 Egyptian sibling patients suspected of Canavan disease (CD); study revealed homozygosity for substitution T530C (Ile177Thr) in exon 4 of the ASPA gene in both sibs; substitution T530C (Ile177Thr) results in a novel missense mutation causing a CD phenotype with severe clinical characteristics PMID: 24036223
    2. Four ASPA missense mutations associated with Canavan disease are structurally characterized. PMID: 25003821
    3. Definitive evidence is presented to show that the recombinantly-expressed human aspartoacylase is not a glycoprotein. PMID: 24632142
    4. This is the first case report of ASPA mutation studies in Canavan disease from Indian subcontinent. PMID: 22878930
    5. a novel mutation Y88X within the aspartoacylase gene in a consanguineous family with an affected child diagnosed as Canavan disease. PMID: 22468686
    6. Human aspartoacylase gene expression was high not only in brain and kidney, but also in lung and liver. PMID: 22750302
    7. Gene ASPA (NM_000049) was undertaken to sequence for mutation analysis. PMID: 22219087
    8. We report on an Italian female patient with Canavan disease due to a missense mutation of the aspartoacylase gene and a 17p13.3 chromosomal microdeletion PMID: 22019069
    9. the ASPA gene was analysed in 22 unrelated non-Jewish patients with Canavan disease, and 24 different mutations were found PMID: 12638939
    10. Mild-onset presentation of Canavan's disease associated with novel G212A point mutation in aspartoacylase gene PMID: 16437572
    11. molecular weight of the purified enzyme is higher than predicted, suggesting the presence of post-translational modifications. Deglycosylation of aspartoacylase or mutation at glycosylation site causes decreased enzyme stability and catalytic activity PMID: 16669630
    12. a green fluorescent protein-human ASPA fusion protein larger than the permissible size for the nuclear pore complex was enzymatically active and showed mixed nuclear-cytoplasmic distribution. PMID: 16935940
    13. The finding that wild-type and Glu178Asp have the same K(m) but different k(cat) values confirms the idea that the carboxylate group contributes importantly to the enzymatic activity of aspartoacylase. PMID: 17027983
    14. the N-terminal domain of aspartoacylase adopts a protein fold similar to that of zinc-dependent hydrolases related to carboxypeptidases A PMID: 17194761
    15. These results show that aspartoacylase is a member of the caboxypeptidase A family and offer novel explanations for most loss-of-function aspartoacylase mutations associated with Canavan Disease. PMID: 17391648
    16. New structure of human aspartoacylase complexed with a catalytic intermediate analogue, N-phosphonomethyl- l-aspartate, supports a carboxypeptidase-type mechanism for hydrolysis of the amide bond of the substrate, N-acetyl- l-aspartate. PMID: 18293939
