| Description: Membrane rafts are rich in cholesterol, sphingolipids, and GPI-linked proteins. The bilayer is thicker in rafts than in the surrounding membrane. The proteins coalesce and form nanometer-sized dynamic raft domains, which may be stabilized by interactions with actin fibers. Rafts can associate to form larger structures (“platforms”). Certain proteins interact preferentially with rafts (orange shading), while others do not (brown shading) or are excluded.
