Polyclonal Goat Affinity Purified E B
SMPD1 (Sphingomyelin phosphodiesterase 1; also ASM) is a 70-85kD member of the acid sphingomyelinase family of enzymes. It is a monomeric lysosomal enzyme that converts sphingomyelin (a plasma membrane lipid) into ceramide through the removal of phosphorylcholine. This generates second messenger components that participate in signal transduction. Mature human SMPD1 is 583aa in length. It contains one saposin B-type domain (aa85-169) that likely interacts with sphingomyelin, and a catalytic region (aa267-363). There are multiple isoforms. One is 57kD in size and results from proteolytic cleavage between Pro179-Pro197. Three others show aa substitutions; a 56 aa substitution for aa1-361, a two aa substitution for aa 363-629, and a 12aa substitution for aa363-418. Over aa62-628, human SMPD1 is 86% aa identical to mouse SMPD1.
Suitable for use in ELISA and Western Blot. Other applications not tested.
