Abstract

Carboxy terminal BRCT domains of the breast cancer susceptibility gene 1 (BRCA1) bind to phosphorylated proteins through a pSXXF consensus recognition motif. We report a systematic structure-activity relationship study that maps the BRCT(BRCA1)-pSXXF binding interface, leading to identification of peptides with nanomolar binding affinities comparable to those of the previously reported 13-mer peptides and providing a clear description of the pSXXF-BRCT interface, which is essential for developing small molecule inhibitors via the peptidomimetic approach.
