Recombinant Human 2'-5'-Oligoadenylate Synthetase 1, 40/46kDa, His-tagged

Cat. No.: OAS1-1399H
Product Overview: OAS1 Human Recombinant fused with 20 amino acid His tag at N-terminus produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 384 amino acids (1-364 a.a.) and having a molecular mass of 43.9kDa. The OAS1 is purified by proprietary chromatographic techniques.
Description: OAS1 enzyme is a member of the 2μ,5μ-oligoadenylate synthetase family. OAS1 is induced by interferons and uses adenosine triphosphate in 2μ-specific nucleotidyl transfer reactions to synthesize 2μ,5μ-oligoadenylates(2-5As). These molecules in turn activate latent RNase L resulting in viral RNA degradation and the inhibition of viral replication. OAS1 may have a role in mediating resistance to virus infection, control of cell growth, differentiation, and apoptosis. OAS1 binds double-stranded RNA and polymerizes ATP into PPP (A2"P5"A)N oligomers, which activate the latent RNase L that, once activated, cleaves single-stranded RNAs. OAS1 gene mutations are been linked to host susceptibility to viral infection. OSA1 gene polymorphisms are linked to the outcome of hepatitis C virus infection. Furthermore, OAS1 gene polymorphisms are linked to the susceptibility to severe acute respiratory syndrome.
