| Synonym | U2 small nuclear ribonucleoprotein A', U2 snRNP A', SNRPA1, Lea1. |
| Background | U2 small nuclear ribonucleoprotein A (SNRPA1), a 255 amino acid protein, is a component of the U2 snRNP which forms a complex with U2 snRNP B (U2B). U2 snRNP A and U2 snRNP B form together a complex which binds to the U2 snRNA hairpin IV. The configuration of the U2 snRNP A/U2 snRNP B dimer and the delicate variations of a few key residues regulate the snRNP-RNA-binding specificity. |
| Description | SNRPA1 Human Recombinant expressed in E.Coli is a single, non-glycosylated polypeptide chain containing 275a.a. (1-255 a.a.) and having a molecular weight of 30.5kDa. SNRPA1 is fused to a 20a.a. His-tag at N-terminus and purified by unique purification methods. |
