Sphingomyelin: What is it good for?

Abstract

Sphingomyelin has been considered as a merely structural lipid for many years. However, this organelle-specific lipid has many other roles, including increasing membrane molecular order, acting as a source of ceramide in cell signaling and apoptosis, and forming clusters/nanodomains with cholesterol and ceramide. This contribution is dedicated to Professor E. Carafoli, on occasion of his 90th anniversary.
