The Ras p21 family of guanine nucleotide proteins has been widely studied in view of its role in signal transduction pathways and high frequency of mutations in human malignancies. The founding members of the Ras family (H-, K- and N-Ras p21) are members of a much larger superfamily of related proteins. Six members of this family, Rap 1A, Rap 1B, Rap 2, R-Ras, Ral A and Ral B, exhibit approximately 50% amino acid homology to Ras. The mammalian Rho proteins (Rho A, B, C, 6, 7 and 8) are approximately 30% homologous to Ras and are expressed in a wide range of cell types. Three Rho-related GTPases Rnd1 (Rho 6), Rnd2 (Rho 7), and Rnd3 (Rho 8 or Rho E) form a distinct branch of the Rho family since they differ from other Rho proteins in size, charge, and biochemical properties. Rnd proteins are likely to be farnesylated, and appear to be constitutively in the activated GTP-bound form. Rnd proteins act as negative regulators of Actin assembly and of cell adhesion. Rnd2 binds to SgK223 (sugen kinase 223) in a GTP-dependent manner. Rnd2-bound SgK223 stimulates Rho A activity and induces cell contraction to regulate neurite outgrowth.
