>cd04129 Rho2 Rho2 subfamily. Rho2 is a fungal GTPase that plays a role in cell morphogenesis, control of cell wall integrity, control of growth polarity, and maintenance of growth direction. Rho2 activates the protein kinase C homolog Pck2, and Pck2 controls Mok1, the major (1-3) alpha-D-glucan synthase. Together with Rho1 (RhoA), Rho2 regulates the construction of the cell wall. Unlike Rho1, Rho2 is not an essential protein, but its overexpression is lethal. Most Rho proteins contain a lipid modification site at the C-terminus, with a typical sequence motif CaaX, where a = an aliphatic amino acid and X = any amino acid. Lipid binding is essential for proper intracellular localization via membrane attachment. As with other Rho family GTPases, the GDP/GTP cycling is regulated by GEFs (guanine nucleotide exchange factors), GAPs (GTPase-activating proteins) and GDIs (guanine nucleotide dissociation inhibitors).
