Lipid Rafts Definition. Eration of a definition for lipid rafts in an ad hoc session on the final day of the meeting. By definition Lipid rafts are dynamic assemblies of proteins and lipids that float freely within the liquid-disordered bilayer of cellular membranes but can also cluster to form larger ordered platforms Simons and Ehehalt 2002. Based on this definition rafts have been correlated with a variety of signaling and sorting properties of membrane components. Internalization of ligands and receptors by these domains occurs via a process defined as raft-dependent endocytosis.

The lipid raft hypothesis postulates that lipidlipid interactions can laterally organize biological membranes into domains of distinct structures compositions and functions. This definition was subsequently modified to introduce the notion that lipid rafts correspond to membrane areas stabilized by the presence of cholesterol within a liquid-ordered phase. The plasma membranes of cells contain combinations of glycosphingolipids and protein receptors organized in glycolipoprotein microdomains termed lipid rafts. In fact many signaling molecules have been shown to be associated with lipid rafts. Lipid rafts are dynamic and shifting assemblies of sphingolipids cholesterol glycosphingolipids and proteins forming platforms or lipid microdomains for the organization and dynamic contact of molecules involved in several molecular and cellular processes such as ligand affinity effector specificity signal transduction membrane sorting and receptor trafficking and recycling.

This definition was subsequently modified to introduce the notion that lipid rafts correspond to membrane areas stabilized by the presence of cholesterol within a liquid-ordered phase. Lipid rafts were originally defined as membrane domains ie ordered structures created as a consequence of the lateral segregation of sphingolipids and differing from the surrounding membrane in their molecular composition and properties. The first operational definition of lipid rafts came with the demonstration that sphingolipids and GPI-anchored proteins are insoluble in a cold detergent extraction Brown and Rose 1992 and literally float like a raft to the top of a density gradient as a separable cholesterol-dependent fraction. Eration of a definition for lipid rafts in an ad hoc session on the final day of the meeting. The definition adopted by the group was as follows.
