| Formulation |
The DBR1 solution (0.5mg/ml) contains 20mM Tris-HCl buffer (pH8.0), 0.15M NaCl, 1mM DTT and 20% glycerol. |
| Purity |
Greater than 90.0% as determined by SDS-PAGE. |
| Description |
DBR1 Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 340 amino acids (228-544) and having a molecular mass of 38kDa (molecular size on SDS-PAGE will appear higher).DBR1 is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. |
| Protein Background |
DBR1 is an RNA lariat debranching enzyme which hydrolyzes 2'-5' prime branched phosphodiester bonds. The encoded protein specifically targets the bonds at the branch point of eliminated lariat intron RNA, transforming them to linear molecules which are then degraded. Additionally, DBR1 takes part in retroviral replication. |
| Expression host |
Escherichia Coli. |
| Synonyms |
Debranching RNA Lariats 1, Lariat Debranching Enzyme, Debranching Enzyme Homolog 1, RNA Lariat Debranching Enzyme, EC 3.1.-.-. |
| Reagent Appearance |
Sterile Filtered clear 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. |
