Recombinant Human U2 Small Nuclear RNA Auxiliary Factor 1

Source : Escherichia Coli. U2AF1 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 263 amino acids (1-240 a.a) and having a molecular mass of 30.3kDa.U2AF1 is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. U2AF1 is a member of the splicing factor SR family. U2 auxiliary factor, comprising a large and a small subunit, is a non-snRNP protein essential for the binding of U2 snRNP to the pre-mRNA branch site.U2AF1 is the small subunit which plays a vital role in both constitutive and enhancer-dependent RNA splicing by directly mediating interactions between the large subunit and proteins bound to the enhancers. U2 small nuclear RNA auxiliary factor 1 (U2AF1) is a protein-coding gene. Among the diseases which are associated with U2AF1:Myoclonus Epilepsy and progressive Myoclonus Epilepsy.

Greater than 90.0% as determined by SDS-PAGE.

U2AF1 protein solution (1mg/mL) containing 20mM Tris-HCl buffer (pH 8.0), 0.4M UREA and 10% glycerol.

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.
