Plant cell polarity: sterols enter into action after cytokinesis.
Developmental cell - 1 Mar 2008
Jaillais Yvon, Gaude Thierry
Abstract excerpt
In yeast and animal cells, the sterol composition of membranes is a key factor that controls the polarity of membrane proteins by regulating their intracellular trafficking or lateral diffusion. A recent study in Nature Cell Biology demonstrates that plant sterols play a major role in the acquisition of cell polarity by modulating endocytosis after cell division.
