Protein Function
Converts sphingomyelin to ceramide. Also has phospholipase C activities toward 1,2-diacylglycerolphosphocholine and 1,2-diacylglycerolphosphoglycerol.
Background
Sphingomyelin phosphodiesterase 1 (SMPD1), also known as acid sphingomyelinase (ASM), is an enzyme that in humans is encoded by the SMPD1 gene. This gene is mapped to 11p15.4. The protein encoded by this gene is a lysosomal acid sphingomyelinase that converts sphingomyelin to ceramide. The encoded protein also has phospholipase C activity. Defects in this gene are a cause of Niemann-Pick disease type A (NPA) and Niemann-Pick disease type B (NPB). Multiple transcript variants encoding different isoforms have been identified. Sphingomyelin phosphodiesterase 1 belongs to the sphingomyelin phosphodiesterase family.
Reproducibility
Reproducibility
To assay reproducibility, three samples with differing target protein concentrations were assayed using four different lots.
