ARSA (arylsulfatase A) is a lysosomal sulfatase. This gene maps to human chromosome 22q13. This protein exists as a dimer and has a molecular weight of 107kDa. It is an acidic glycoprotein. It consists of 507 amino acid residues. Placental arylsulfatase A contains a putative 18 amino acid long signal peptide, preceding its N- terminal. ARSA is predicted to have three N-glycosylation sites.
Synonyms: Anti-ASA antibody produced in rabbit; Anti-Arylsulfatase A precursor antibody produced in rabbit; Anti-Cerebroside-sulfatase antibody produced in rabbit
Storage: -20C
Application: Anti-ARSA antibody is suitable for co-immunoprecipitation, co-localization and flow cytometry.Anti-ARSA antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.
Biochem Physiol Actions: ARSA (arylsulfatase A) requires post-translational modification to become catalytically active. This involves the oxidation of the -CH2SH group of a cysteine residue to aldehyde. Lack of this modification results in inactive enzyme, which causes the lysosomal storage disorder called multiple sulfatase deficiency. Complete or partial inactivation of this gene leads to Metachromatic leukodystrophy (MLD), which is a lysosomal storage disease. It is characterized by the accumulation of cerebroside sulfate in lysosomes. ARSA pseudo-deficiency is caused in individuals who are homozygous for the allele, which results in significant loss of ARSA activity. However, the activity is sufficient for normal cerebroside catabolism and results in clinically healthy phenotype.
