Structure of the Rab14-RCP complex.
A, ribbon model of Rab14 (gray) in complex with RCP homodimer (yellow and orange). The switch regions are indicated in red and blue; GTP is a green stick model, and Mg2+ is shown as a sphere. B, superposition of Rab14 (GTP) and Rab14 (GDP; PDB code 4drz). RCP is not shown for clarity, and the disulfide bridge is represented by sticks (purple). C, refined electron density map (2Fo-Fc, 1σ) of Rab14-RCP complex around the intramolecular disulfide bond.
