Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues at the carboxyl terminus of human ASM. Antibody was purified by protein A and peptide affinity chromatography.
Sphingomyelinases (SMases) catalyze the hydrolysis of sphingomyelin to produce ceramide and phosphocholine (1). Ceramide is an important bioactive lipid triggering signal transduction involved in cell proliferation, apoptosis and differentiation (1,2). A number of SMases have been described and categorized based on their optimum pH activity, cation dependence, tissue distribution, and subcellular localization (1). These include a lysosomal acid SMase, a Zn++-dependent secreted acid SMase, a membrane-bound Mg++-dependent neutral SMase, a Mg++-independent neutral SMase, and an alkaline SMase.
Acid sphingomyelinase (ASM or SMPD1) is a lysosomal enzyme responsible for the hydrolysis of sphingomyelin to ceramide and phosphocholine. The ASM gene encodes three proteins, ASM-1, ASM-2, and ASM-3, of which ASM-1 is the only catalytically active enzyme (3,4). ASM-1 can exist as a 70 kDa form as well as a 57 kDa proteoytic product (5). Expression of ASM is induced during monocytic cell differentiation (6). Defects in the ASM gene are associated with type A and type B Niemann-Pick disease (7).
