deaf14 mice harbor a nonsense mutation in Aspa. (A) Manhattan plot showing probability of linkage to deaf14 locus across the genome. A LOD score above 3 is indicative of linkage. This was observed for a single peak on chromosome 11, indicating that the deaf14 mutation is on this chromosome. (B) Haplotypes of 140 N1F1 mice for SNPs on chromosome 11. Mice were deemed affected or unaffected based on their click ABR. SNP identity is indicated on the left and chromosomal location is indicated on the right. The number of mice with each haplotype is indicated below. SNP locations were taken from Genome Reference Consortium Mouse Build 38 patch release 1 (GRCm38.p1). (C) DNA sequence of Aspa exon 3 in +/+ (upper panel) and deaf14/deaf14 mouse (lower panel). A c.516T>A mutation (*) is predicted to encode a p.Y172X premature termination of translation in the deaf14/deaf14 mouse. (D) Western blot of p26 whole brain lysates probed with anti-ASPA (upper panel) and anti-actin (lower panel) antibodies. The upper panel shows a band at 35 kDa, the predicted molecular weight of ASPA, in Aspa+/+ and Aspa+/deaf14 brain that is not present in Aspadeaf14/deaf14 brain. The faint band in the Aspadeaf14/deaf14 lane (*) is of a slightly higher molecular weight and is also present in the two other lanes, albeit almost obscured by the ASPA band. This is likely to be a non-specific band. The lower panel demonstrates that equal amounts of protein were loaded in each lane. NS, non-specific band; 14, deaf14.

Aspartoacylase also known by its abbreviation ASPA is an enzyme that breaks down N-acetyl-L-aspartate into aspartate and acetate. It has a mass of about 60 kDa. ASPA is highly expressed in the brain especially in oligodendrocytes which are a type of central nervous system cell responsible for producing the myelin sheath that surrounds nerve cells. Its enzymatic activity is dependent on divalent metal ions which are required for its function.
Biological function summary

ASPA plays an important role in myelin sheath maintenance and acetate metabolism. This protein doesn't form part of a complex but acts independently in the cytoplasm and peroxisomes of cells. Its function is significant for the provision of acetate for lipid synthesis which is necessary for myelin production. By regulating N-acetyl-L-aspartate levels in the brain ASPA activity is linked directly to protecting nerve cells' structural integrity.

Pathways

The ASPA enzyme is involved in the aspartate and acetyl-CoA pathways which are central to cellular energy balance and lipid metabolism. Its enzymatic role facilitates the recycling of acetate which is vital to the synthesis of myelin lipids. The relationship of ASPA with enzymes like acetyl-CoA synthetase highlights its involvement in broader biochemical pathways fundamental to cell metabolism and growth.

Deficiencies in ASPA are linked to Canavan disease a rare and inherited neurodegenerative condition characterized by white matter sponginess and loss of motor skills. This disorder results from mutations in the ASPA gene leading to dysfunctional enzyme activity. Additionally changes in ASPA expression levels might contribute to demyelinating disorders where proteins like myelin basic protein are also often involved making ASPA an important target for studies exploring nervous system diseases.

靶点信息

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 acts as a scavenger of NAA from body fluids.
