Details The amino acid sequence, the chemical shift assignment, and the NOESY spectra were input for the automated NOESY peak picking and NOE assignment method of ATNOS/CANDID/CYANA. The results of ATNOS/CANDID/CYANA were refined by manual peak adjustment and additional calculations in CYANA. The 20 conformers from the ATNOS/CANDID cycle 7 with the lowest residual CYANA target function values were energy-minimized in a water shell with the program CNS.

Additional NMR Experimental Information
1 The following spectra were used to achieve the sequence-specific backbone and side chain assignments of all aliphatic residues: 2D [1H,15N]-HSQC, 2D [1H,13C]-HSQC, 3D HNCACB, 3D CBCA(CO)NH, 3D CC(CO)NH, 3D HNCO, 3D HNCA, 3D HBHA(CO)NH, 3D 15N-resolved [1H,1H]-TOCSY, 3D HC(C)H-TOCSY6. The 2D [1H,1H]-NOESY, 2D [1H,1H]-TOCSY and 2D [1H,1H]-COSY spectra of the Spinophilin493-602 sample in D2O solution after complete H/D exchange of the labile protons were used for the assignment of the aromatic side chains. The NMR spectra were processed with Topspin1.3, and analyzed with the CARA software package. Spectra used for the structure calculation were: 3D 15N-resolved [1H,1H]-NOESY, 3D 13C-resolved [1H,1H]-NOESY (mixing time of 85 ms) and 2D [1H,1H]-NOESY (mixing time 85 ms, D2O solution).
