Abstract:
Acid sphingomyelinase (ASM) plays an important role in normal membrane turnover through the hydrolysis of sphingomyelin, and is one of the key enzymes responsible for the production of ceramide. ASM activity is deficient in the genetic disorder Types A and B Niemann-Pick disease (NPD). ASM knockout (ASMKO) mice were originally constructed to study this disorder, and numerous defects in ceramide-related signaling have been shown. Studies in these mice have further suggested that ASM may be involved in the pathogenesis of several common diseases through the reorganization of membrane microdomains. This review will focus on the role of ASM in membrane biology, with a specific emphasis on what a rare genetic disorder (NPD) has taught us about more common events.

Eukaryotic flippases are type-IV P-type ATPases or P4-ATPases belonging to P-type ATPase family proteins that are membrane-bound pumps involved in the ATP-mediated transport of ions and molecules across the membrane. Flippases flip specific phospholipids from the outer to the inner leaflet of a membrane. All P4-ATPases have one...
