Membrane cholesterol and the regulation of signal transduction

Biochem Soc Trans. 2004 Feb;32(Pt 1):65-9. doi: 10.1042/bst0320065.

Abstract

The plasma membrane of mammalian cells consists of microdomains differing in lipid and protein composition. Two distinct classes of cholesterol/sphingolipid microdomain (caveolae and lipid rafts) are assembly points for transmembrane signalling complexes. Recent evidence suggests that transient changes in cholesterol content may be important in regulating signal transduction.
