- Product Overview:
The DNA methyltransferase 3 (DNMT3) family of DNMT proteins establish intial methylation of cytosines to form 5-methylcytosine at CpG (cytosine-phosphate-guanine) sites. Once methylation is established on DNA, DNMT1 protein is responsible for maintaining the CpG methylation pattern during chromosome replication. The DNMT3 family includes the two active members, DNMT3a and DNMT3b, and the regulatory factor DNMT3-like protein (DNMT3L). DNMT3L contains a cysteine-rich, DNMT3/ATRX homology or ATRX-DNMT3-DNMT3L (ADD) domain, however it lacks the proline-tryptophan-tryptophan-proline (PWWP) domain, required for non-specific DNA binding. The ADD domain of DNMT3L is responsible for specifically binding to unmethylated histone H3 lysine 4 (H3K4me0).{19546} DNMT3L also lacks the conserved residues in the C-terminal DNA MTase domain of DNMT3a and 3b that are required for activity.{19542} However, DNMT3L is required to stimulate the DNA methylation activity of DNMT3a and 3b through interactions with the catalytic domain of DNMT3a and 3b.{19545,19543,19544}
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.
