Description

DEFINITION

Sphingomyelin phosphodiesterase or simply Sphingomyelinase (SMase) is a hydrolase enzyme that breaks sphingomyelin (SM) down into phosphocholine and ceramide. The activation of SMase has been suggested as a major route for the production of ceramide in response to cellular stresses.
