Smpd1 Antibody / Acid sphingomyelinase / aSMase

Sphingomyelin phosphodiesterase 1 (SMPD1), also known as acid sphingomyelinase (ASM or aSMase), is an enzyme that in humans is encoded by the SMPD1 gene. Enables acid sphingomyelin phosphodiesterase activity and zinc ion binding activity. Involved in ceramide biosynthetic process; positive regulation of apoptotic process; and response to ionizing radiation. Acts upstream of or within ceramide metabolic process; cholesterol metabolic process; and sphingomyelin catabolic process. Located in extracellular space. Is expressed in several structures, including alimentary system; integumental system; nervous system; sensory organ; and skeleton. Used to study Niemann-Pick disease. Human ortholog(s) of this gene implicated in Niemann-Pick disease; Niemann-Pick disease type A; and Niemann-Pick disease type B. Orthologous to human SMPD1 (sphingomyelin phosphodiesterase 1).
