- Product Overview:
The BRCA1 C-terminal (BRCT) domain is a modular unit of ~100 amino acids that folds independently and recognizes linear phosphoserine or phosphothreonine regions to mediate protein-protein and protein-DNA interactions.{23632} BRCT domains were initially recognized in the C-terminal region of the breast cancer protein BRCA1, as well as the p53 binding protein (53BP1; TP53BP1), and the yeast cell cycle checkpoint protein RAD9.{23633} BRCT domains often occur as tandem repeats at the C-terminal end of several proteins that are functionally diverse.{22097} Most BRCT domain-containing proteins participate in DNA-damage checkpoint control or DNA-repair pathways, or both.{23634,23633} Thus, BRCT domain-containing proteins likely participate in the cellular response to DNA damage. The BRCT domains of TP53BP1 bind to the DNA binding domain region of the tumor suppressor protein p53. The residues of p53 involved in this binding are often mutated in cancer.{23629,23631,23630} Binding of TP53BP1 to p53 occurs through the first BRCT domain and the inter-domain linker between the BRCT repeats. TP53BP1 binds to wild-type but not mutant p53 protein, which was believed to mediate p53 tumor suppressor function.{23631} More recently, recruitment to DNA double strand breaks has shown to be mediated by the TP53BP1 tudor domain region binding to dimethylated lysine on p53 and histone H4.{22372,22371} This product contains the BRCT domains of TP53BP1.
Cayman Chemical’s mission is to help make research possible by supplying scientists worldwide with the basic research tools necessary for advancing human and animal health. Our utmost commitment to healthcare researchers is to offer the highest quality products with an affordable pricing policy.
Our scientists are experts in the synthesis, purification, and characterization of biochemicals ranging from small drug-like heterocycles to complex biolipids, fatty acids, and many others. We are also highly skilled in all aspects of assay and antibody development, protein expression, crystallization, and structure determination.
Over the past thirty years, Cayman developed a deep knowledge base in lipid biochemistry, including research involving the arachidonic acid cascade, inositol phosphates, and cannabinoids. This knowledge enabled the production of reagents of exceptional quality for cancer, oxidative injury, epigenetics, neuroscience, inflammation, metabolism, and many additional lines of research.
Our organic and analytical chemists specialize in the rapid development of manufacturing processes and analytical methods to carry out clinical and commercial GMP-API production. Pre-clinical drug discovery efforts are currently underway in the areas of bone restoration and repair, muscular dystrophy, oncology, and inflammation. A separate group of Ph.D.-level scientists are dedicated to offering Hit-to-Lead Discovery and Profiling Services for epigenetic targets. Our knowledgeable chemists can be contracted to perform complete sample analysis for analytes measured by the majority of our assays. We also offer a wide range of analytical services using LC-MS/MS, HPLC, GC, and many other techniques.
