Predicted to enable acid sphingomyelin phosphodiesterase activity; channel inhibitor activity; and zinc ion binding activity. Involved in several processes, including ceramide biosynthetic process; positive regulation of apoptotic process; and response to cocaine. Located in extracellular space and lamellar body. Used to study Wilson 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); PARTICIPATES IN ceramide signaling pathway; FasL mediated signaling pathway; Trail mediated signaling pathway; INTERACTS WITH 17alpha-ethynylestradiol; 2,3,7,8-tetrachlorodibenzodioxine; 3,3',4,4',5-pentachlorobiphenyl.
