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.

摘要

乳腺癌易感基因 1（BRCA1）的羧基末端 BRCT 结构域通过 pSXXF 共有识别基序与磷酸化蛋白结合。我们报告了一项系统的结构-活性关系研究，该研究绘制了 BRCT（BRCA1）-pSXXF 结合界面，鉴定出具有纳摩尔结合亲和力的肽，与先前报道的 13 肽相当，并提供了 pSXXF-BRCT 界面的清晰描述，这对于通过肽模拟方法开发小分子抑制剂至关重要。
