Structural basis of phosphopeptide recognition by the BRCT domain of BRCA1.
R.S.Williams, M.S.Lee, D.D.Hau, J.N.Glover.
The BRCT repeats in BRCA1 are essential for its tumor suppressor activity and interact with phosphorylated protein targets containing the sequence pSer-X-X-Phe, where X indicates any residue. The structure of the tandem BRCA1 BRCT repeats bound to an optimized phosphopeptide reveals that the N-terminal repeat harbors a conserved BRCT phosphoserine-binding pocket, while the interface between the repeats forms a hydrophobic groove that recognizes the phenylalanine. Crystallographic and biochemical data suggest that the structural integrity of both binding sites is essential for peptide recognition. The diminished peptide-binding capacity observed for cancer-associated BRCA1-BRCT variants may explain the enhanced cancer risks associated with these mutations.

Figure 1.
Figure 1. Overview of the BRCA1 BRCT -peptide complex. (a) -strands in the BRCT domain are green and -helices are yellow. The peptide is blue. The BRCT residues that recognize the pSer and Phe(+3) residues have transparent surfaces. (b) Amino acid sequence of the human BRCA1 BRCT domain with secondary structure. The residues that contact the phosphoserine are shaded blue, and those that form the Phe(+3)-binding pocket are marked by red circles. Missense mutations assayed for interactions with the peptide are above the sequence. Residues involved in inter-repeat BRCT interactions are boxed. (c) Structural arrangement of one of the three similar dimers in the crystallographic asymmetric unit.

Hydrogen bonds and salt bridges are indicated by dotted lines. (b) Conformational variability of phosphopeptide binding. Overlay of the five independent peptide structures in the crystallographic asymmetric unit. The BRCT C atoms of each of the BRCT -peptide complexes were superimposed to generate the overlay. (c) Electrostatic surface representation of the BRCT domain with the pSer- and Phe-binding pockets; the peptide is gray.

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.
