Publication Abstract from PubMed

The crystal structure of the NTF2-like domain of the Drosophila homolog of Ras GTPase SH3 Binding Protein (G3BP), Rasputin, was determined at 2.7A resolution. The overall structure is highly similar to nuclear transport factor 2: It is a homodimer comprised of a beta-sheet and three alpha-helices forming a cone-like shape. However, known binding sites for RanGDP and FxFG containing peptides show electrostatic and steric differences compared to nuclear transport factor 2. A HEPES molecule bound in the structure suggests a new, and possibly physiologically relevant, ligand binding site.
