A<unk>  is a small (~21 kDa) signaling G protein (more specifically a<unk>  of the Ras superfamily.<unk> s have been shown to regulate many aspects of intracellular actin dynamics.<unk> s are found in all eukaryotic organisms as well as in yeasts and some plants. Three members of the family have been particularly well-studied: RhoA, Rac1 and Cdc42.<unk>  proteins have been described as ‘molecular switches’ and have been described to play a role in cell proliferation, apoptosis, cell division, gene expression and multiple other common cellular functions.
