The ins and outs of cell-polarity decisions

Abstract

The guanine-nucleotide-exchange factor Cdc24 is a critical regulator of cell polarity. Far1 is a key player in Cdc24 regulation, controlling Cdc24 activity in budding yeast by regulating its subcellular localization in response to two very different signals — one external and one internal.
