General description

SNRNP200 (small nuclear riboprotein 200) is a spliceosome RNA helicase, that belongs to the Ski2-like subfamily. It is located on chromosome 2q11.2 and codes for Brr2, a 200kDa helicase. It consists of 45 exons.

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project 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. We also provide Prestige Antibodies® protocols and other useful information.

Biochem/physiol Actions

SNRNP200 (small nuclear riboprotein 200) plays a major role in unwinding U4/U6 snRNA to give a highly structured RNA interaction network required for the activation of the spliceosome. Attenuation of SNRNP200 in human cells reduces the production of interferon-β (IFNB1) and increases susceptibility to viral infection. It controls innate immune responses of Sendai virus infected human MDM (monocyte-derived macrophages). It positively modulates the activation of IRF3 (interferon regulatory factor 3) via interaction with TANK kinase 1 (TBK1). Suppression of SNRNP200 reduces antiviral immune response upon Sendai virus infection.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.
