Secondary Information

Protein Function Inhibits GDP/GTP exchange reaction of RhoB.
Biochemical Properties The NH2-terminal alpha helix of RhoGDI-3 is strongly amphipatic.Contained 21 additional amino acids in the NH2-terminal region .The incomplete RhoGDI-3 protein, lacking the first 68 NH2-terminal residues, could only interact with the GTP-bound RhoB-G14V protein. α-loop-α-loop secondary structure is important for specificity of the interaction between GDI-3 and Rho proteins.
