Regulation of raft architecture

Summary: Raft membrane domains are envisioned as lateral assemblies of cholesterol and sphingolipids which adopt a liquid-ordered membrane phase. Our understanding of the raft architecture in cell membranes is developing rapidly. The current view describes raft domains as small and highly dynamic subdomains of cell membranes. The size and stability of raft domains are essential parameters which determine the function of raft domains in cells. Here we discuss how the architecture and stability of raft domains is regulated by oligomerisation of raft components and by modulation of their molecular compositio
