OAS1 (2'-5'-oligoadenylate synthetase 1, 40/46kDa) is an interferon-inducible protein beloonging to the 2'-5'-Oligoadenylate synthetase family. It plays an essential role in host defense system against viral infection. On its surface, it consists of two dsRNA-binding sites located ~30 Å apart.
Synonyms: Anti-(2-5'oligo(A) synthetase 1; Anti-2'-5'-oligoadenylate synthetase 1; Anti-2-5A synthetase 1; Anti-E18/E16; Anti-p46/p42 OAS
Storage: -20C
Application: All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem Physiol Actions: 2'-5'-oligoadenylate synthetase 1 is an enzyme encoded by the OAS1 gene in humans. It is one of the major interferon-inducible proteins and a critical component of the host defense system against viral infection. It plays a central role in innate immune system detection of cytoplasmic double-stranded RNA (dsRNA) and in the promotion of host antiviral responses. It possesses antiviral activity and other anti-proliferative roles.
