Cell biology: Earthworms and lipid couriers
Sean Munro1
Abstract
Lipids can hop between cellular compartments without using the transport vesicles that carry proteins. A key molecule involved in conveying the lipid ceramide has at last been uncovered.
Slice open any eukaryotic cell and you will find it packed with membrane-bounded compartments, each with a characteristic set of resident proteins and lipids. Many of these molecules begin their lives in the endoplasmic reticulum (ER), a large network of intracellular membranes.
