Acid Sphingomyelinase Regulates the Localization and Trafficking of Palmitoylated Proteins [PDF]
In human, loss of Acid Sphingomeylinase (ASM/SMPD1) causes Niemann-Pick Disease, type A. ASM hydrolyzes sphingomyelins to produce ceramides but protein targets of ASM remain largely unclear. ...

Sphingolipids as emerging mediators in retina degeneration [PDF]
The sphingolipids ceramide (Cer), sphingosine-1-phosphate (S1P), sphingosine (Sph), and ceramide-1-phosphate (C1P) are key signaling molecules that regulate major cellular functions.

Acid Sphingomyelinase-deficient Macrophages Have Defective Cholesterol Trafficking and Efflux [PDF]
Cholesterol efflux from macrophage foam cells, a key step in reverse cholesterol transport, requires trafficking of cholesterol from intracellular sites to the plasma membrane. Sphingomyelin is a cholesterol-binding molecule that transiently exists with cholesterol in endosomes and lysosomes but is rapidly hydrolyzed by lysosomal sphingomyelinase (L ...

Reproductive Pathology and Sperm Physiology in Acid Sphingomyelinase-Deficient Mice [PDF]
Types A and B Niemann-Pick disease (NPD) are lysosomal storage disorders resulting from the deficient activity of acid sphingomyelinase (ASM). In this manuscript we report the pathobiology of male gonadal tissue and sperm in a knockout mouse model of NPD and demonstrate the importance of ASM for normal sperm maturation and function.

Niemann-Pick Disease: Seven Questions about it
Acid sphingomyelinase deficiency is a rare hereditary disease caused by enzyme deficiency due to mutations in the SMPD1 gene. Decreased enzyme activity leads to accumulation of sphingomyelin in lysosomes.

Human acid sphingomyelinase structures provide insight to molecular basis of Niemann–Pick disease
Genetic alterations in the protein acid sphingomyelinase (ASM) lead to ASM deficiency and have been associated with Niemann–Pick disease. Here, the authors report the crystal structures of ASM alone and bound to its product, and discuss the catalytic ...
