Structural basis of phospho-peptide recognition by the BRCT domain of BRCA1, structure with phosphopeptide
Contents |
Overview
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.
