Background

As a member of the sulfatase family, ARSA is required for the lysosomal degradation of cerebroside-3-sulfate, a sphingolipid sulfate ester and a major constituent of the myelin sheet (1). The ARSA deficiency results in metachromatic leukodystrophy (MLD), a lysosomal storage disease in the central and peripheral nervous systems with severe and progressive neurological symptoms (2). The deduced amino acid sequence of human ARSA consists of a signal peptide (residues 1-18) and a mature chain (residues 19-507) (3). Human ARSA has a predicted molecular mass of approximately 53 kDa and an apparent molecular mass of approximately 63 kDa in SDS-PAGE. The amino acid sequence of human ARSA shares 92%, 89%, 87%, and 86% identity with porcine, canine, mouse, and rat ARSA.
