The mystery of membrane organization: composition, regulation and roles of lipid rafts

The mystery of membrane organization: composition, regulation and roles of lipid rafts Cellular membranes are laterally heterogeneous and consist of transient and dynamic domains with varying properties, which prominently include ordered lipid-driven domains that are referred to as lipid (or membrane) rafts. Membrane domains can be induced and regulated by a variety of interactions, which include specific lipid–lipid and lipid–protein interactions, bulk membrane properties, and interactions between membrane components and the underlying cytoskeleton. Advanced microscopy and biochemistry techniques facilitate the study of membrane domains; however, these domains still elude direct in vivo visualization. The multiplicity of possible organizational states and their context-dependent nature most likely account for experimental inconsistencies.

Abstract

Cellular membranes are laterally heterogeneous and consist of transient and dynamic domains with varying properties, which prominently include ordered lipid-driven domains that are referred to as lipid (or membrane) rafts. Membrane domains can be induced and regulated by a variety of interactions, which include specific lipid–lipid and lipid–protein interactions, bulk membrane properties, and interactions between membrane components and the underlying cytoskeleton. Advanced microscopy and biochemistry techniques facilitate the study of membrane domains; however, these domains still elude direct in vivo visualization. The multiplicity of possible organizational states and their context-dependent nature most likely account for experimental inconsistencies. Membrane rafts potentially have crucial physiological roles across cell types that range from immune cells to cancer cells. Membrane domains are conserved throughout the domains of life, which supports their functional importance in biological systems.
