Impact of BRCA1 BRCT Domain Missense Substitutions on Phosphopeptide Recognition
The BRCA1 BRCT domain binds pSer-x-x-Phe motifs in partner proteins to regulate the cellular response to DNA damage. Approximately 120 distinct missense variants have been identified in the BRCA1 BRCT through breast cancer screening, and several of these have been linked to an increased cancer risk. Here we probe the structures and peptide-binding activities of variants that affect the BRCA1 BR...
متن کاملComprehensive analysis of missense variations in the BRCT domain of BRCA1 by structural and functional assays.
Genetic screening of the breast and ovarian cancer susceptibility gene BRCA1 has uncovered a large number of variants of uncertain clinical significance. Here, we use biochemical and cell-based transcriptional assays to assess the structural and functional defects associated with a large set of 117 distinct BRCA1 missense variants within the essential BRCT domain of the BRCA1 protein that have ...
متن کاملFunctional analysis of BRCT missense mutations in BRCA1-mutated Chinese Han familial breast cancer
Breast cancer 1 (BRCA1) is one of the most common tumor suppressor genes in breast cancer. The BRCT domain of BRCA1 has been shown to have a critical role in tumor suppression. In a previous study, two de novo BRCT missense mutations of BRCA1, G1763V and L1786P were identified from Chinese females with familial breast cancer. In the present study, the function of these two novel mutations were ...
متن کاملFunctional Investigation of the Novel BRCA1variant (Glu1661Gly) byComputationalTools andYeastTranscription Activation Assay
Introduction: Mutations in the BRCA1 gene are major risk factors for breast and ovarian cancers. However, the relationship between some BRCA1 mutations and cancer risk remains largely unknown. Cancer risk predictions could be improved by evaluation of the impairment degree in the BRCA1 functions due to a specific mutation. This study aimed to assess the functional effect of a novel variant (Glu...
