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