Structure and ligand recognition of the PB1 domain: a novel protein module binding to the PC motif.
H.Terasawa, Y.Noda, T.Ito, H.Hatanaka, S.Ichikawa, K.Ogura, H.Sumimoto, F.Inagaki.
PB1 domains are novel protein modules capable of binding to target proteins that contain PC motifs. We report here the NMR structure and ligand-binding site of the PB1 domain of the cell polarity establishment protein, Bem1p. In addition, we identify the topology of the PC motif-containing region of Cdc24p by NMR, another cell polarity establishment protein that interacts with Bem1p. The PC motif-containing region is a structural domain offering a scaffold to the PC motif. The chemical shift perturbation experiment and the mutagenesis study show that the PC motif is a major structural element that binds to the PB1 domain. A structural database search reveals close similarity between the Bem1p PB1 domain and the c-Raf1 Ras-binding domain. However, these domains are functionally distinct from each other.

Figure 1.
Figure 1 2D 1H-15N HSQC spectra of (A) Bem PB1 and (B) Cdc24p PCCR. The cross peaks are labeled with one-letter codes of amino acids and residue numbers (SC denotes side-chain resonances). Position 6 of Bem PB1 and Cdc24p PCCR corresponds to residue 472 of Bem1p and 780 of Cdc24p, respectively.
Figure 2.
Figure 2 The 3D structure of Bem PB1. The overall fold of amino acid residues 12 -85 of Bem PB1 is depicted, with the N- and C-termini labeled. (A) Overlay of the 20 final conformers on the average coordinate position for the backbone (N, C^ and C') atoms of residues 12 -55 and 62 -85. Residue numbers corresponding to the beginning and the end of each secondary structural element are shown. (B) Ribbon diagrams of the minimized mean structure of Bem PB1. Both figures were created using the program MOLSCRIPT (Kraulis, 1991). Two of the inner strands ( 1 and 4) are parallel and can be seen in orange, with the other two strands ( 2 and 3) running in an antiparallel manner shown in yellow. The first -helix is shown in dark green and the second one is shown in light green. The notations of these secondary structural elements (a, -helix; b, -strand) are indicated.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
