Product Overview:
Epithelial cell-transforming sequence 2 oncogene (ECT2) is a guanine nucleotide exchange factor (GEF) that catalyzes the exchange of GDP for GTP from small GTPases of the Rho family, such as RhoA, RhoC, Rac1, and Cdc42.{24795} ECT2 GEF activity plays an essential role during cytokinesis.{24792} ECT2 contains a DH (DBL-homology) domain, a pleckstrin homology (PH) domain and tandem BRCT domains.{24794} BRCT domains are modular units of ~100 amino acids that fold independently and recognize linear phosphoserine or phosphothreonine regions to mediate protein-protein and protein-DNA interactions.{23632,22097} BRCT domains were initially recognized in the C-terminal region of the breast cancer protein BRCA1, as well as the p53 binding protein 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} The BRCT domains of ECT2 make intramolecular interactions with the C-terminal DH/PH domains of the protein, thus, masking the catalytic GEF activity for Rho GTPases.{24796} Additionally, release of the autoinhibition by the BRCT domains may be necessary for the proper functioning of ECT2 during cytokinesis.{24796} Expression levels of ECT have been shown to be strongly correlated with prognosis in glioma patients.{24793}

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.
