Lipid droplets: proteins floating on a pool of fat.
Proteins on the surface of lipid storage droplets are crucial to droplet structure and function, but are poorly understood. Recent reports reveal a function for perilipins, major lipid droplet proteins in adipocytes, and show that caveolin proteins can accumulate on lipid droplets.
