Biochem/physiol Actions

Tripartite motif-containing 22 is a protein encoded by the TRIM22 gene in humans and belongs to tripartite motif (TRIM) protein superfamily. The members of this family are important effectors of the innate immune response against viral infections. It is an interferon (IFN)-inducible protein as well as a p53 target gene. It plays a role in viral defense by restricting viral replication and may function as a ubiquitin E3 ligase. This gene is found to exert antiviral activity against RNA viruses, such as hepatitis B virus (HBV), encephalomyocarditis virus (ECMV) and human immunodeficiency virus type 1 (HIV-1). It is involved in the activation of NF-κB. It acts as a positive regulator of NF-κB-mediated transcription.

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.


Corresponding Antigen APREST86655.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
