| Description | HAT1 Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 343 amino acids (20-341 a.a.) and having a molecular mass of 40.1 kDa. The HAT1 is fused to a 21 amino acid His Tag and purified by proprietary chromatographic techniques. |
| Expression host | Escherichia Coli. |
| Formulation | The HAT1 solution contains 20mM Tris-HCl pH-8, 1mM DTT, and 10% glycerol. |
| Product Description | Immunoreactive with all sera of HIV-2 infected individuals. |
| Protein Background | HAT1 is a type B histone acetyltransferase that participates in the rapid acetylation of newly synthesized cytoplasmic histones, which are in turn imported into the nucleus for de novo deposition onto nascent DNA chains. Histone acetylation, mainly of soluble histone H4 at ”Lys-5” and ”Lys-12” and acetylates histone H2A at ”Lys-5”. HAT1 takes part in replication-dependent chromatin assembly. HAT1 acetylates soluble but not nucleosomal histone H4 at lysines 5 and 12, and to a lesser degree, histone H2A at lysine 5. HAT1 has intrinsic substrate specificity that modifies lysine in recognition sequence GXGKXG. |
| Purity | Greater than 90% as determined by SDS-PAGE. |
| Reagent Appearance | Sterile Filtered clear colorless solution. |
| Stability | Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles. |
| Synonyms | EC 2.3.1.48, KAT1, histone acety ltransferase 1, Histone acetyltransferase type B catalytic subunit, HAT1. |
