- Product Overview:
The heterochromatin protein 1 (HP1) family, which consists of three isoforms HP1? (CBX5), HP1? (CBX1) and HP1? (CBX3) are chromatin-associated proteins involved in gene regulation and heterochromatin formation.{20846} CBX proteins have an N-terminal chromodomain, a C-terminal chromoshadow domain, and a hinge domain which connects the two.{23468} Extensive post-translational modifications have been observed and mapped on the CBX proteins.{23471} The chromodomain of CBX5 has been shown to recognize di- and tri-methylated lysine 9 on histone H3 (H3K9me2 and H3K9me3), with a preference for H3K9me3. Binding of CBX5 to methylated histones leads to gene silencing and heterochromatin formation.{20846,20874} H3K9 trimethylation by the methyltransferase SETDB1 creates a binding site for recruitment of CBX5, leading to chromatin condensation and gene silencing.{20845} The chromoshadow domain facilitates protein-protein interactions like homodimerization and recruitment of nuclear proteins involved in transcriptional regulation.{20843} The chromoshadow domain is also responsible for recruitment to sites of DNA damage, where CBX5 helps to reorganize chromatin as part of the DNA damage response system.{20844}
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.
