Organism

Homo sapiens (Human) [Complete proteome]

Taxonomic identifier

9606 [NCBI]

Taxonomic lineage

Eukaryota › Metazoa › Chordata › Craniata › Vertebrata › Euteleostomi › Mammalia › Eutheria › Euarchontoglires › Primates › Haplorrhini › Catarrhini › Hominidae › Homo

Protein attributes

Sequence length	408 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Involved in the hydrolysis of N-acylated or N-acetylated amino acids (except L-aspartate).
Catalytic activity	An N-acyl-L-amino acid + H2O = a carboxylate + an L-amino acid.
Cofactor	Binds 2 zinc ions per subunit.
Subunit structure	Homodimer. Interacts with SPHK1 By similarity.
Subcellular location	Cytoplasm.
Tissue specificity	Expression is highest in kidney, strong in brain and weaker in placenta and spleen. Ref.7
Involvement in disease	Defects in ACY1 are the cause of aminoacylase-1 deficiency (ACY1D) [MIM:609924]. ACY1D results in a metabolic disorder manifesting with encephalopathy, unspecific psychomotor delay, psychomotor delay with atrophy of the vermis and syringomyelia, marked muscular hypotonia or normal clinical features. Epileptic seizures are a frequent feature. All affected individuals exhibit markedly increased urinary excretion of several N-acetylated amino acids. Ref.7 Ref.6 Ref.9
Sequence similarities	Belongs to the peptidase M20A family.
