- Product Overview:
Histone H2A is a core histone that forms a dimer with histone H2B.{46631} Two histone H2A/H2B dimers form an octameric nucleosome with a histone H3/H4 tetramer, around which DNA wraps, allowing it to be condensed. Histone H2A can be post-translationally modified via methylation of the arginine at position 3 by protein arginine methyltransferase 1 (PRMT1), PRMT5, or PRMT6, which is associated with both transcriptional activation and repression.{46198} When methylated by PRMT7, it is associated with DNA damage repair. The arginine residue at position 3 of histone H2A is also subject to citrullination by protein arginine deiminase 4 (PAD4). Histone H2A is ubiquitinated by ubiquitin-specific protease 12 (USP12) during the gastrula stage of Xenopus development.{65096} The post-translational modifications on histone H2A vary between each stage of Xenopus development and are enriched on nucleosomes in Xenopus embryos that contain both active and repressive histone modifications.{65097} Cayman’s Histone H2A (Xenopus, recombinant) protein can be used as a substrate for enzyme activity assays, as well as for Western blot (WB) applications.
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.
