TRIM21, a member of the tripartite motif (TRIM) family, is a part of the RoSSA ribonucleoprotein, which includes a single polypeptide and one of four small RNA molecules. The RoSSA particle localizes to both the cytoplasm and the nucleus (1). RoSSA interacts with autoantigens in patients with Sjogren syndrome and systemic lupus erythematosus (2). TRIM21 also acts as a cytosolic antibody receptor; detection of intracellular antibodies activate immune signaling by stimulating the transcription factor pathways of NF-kappaB, AP-1, IRF3, IRF5, and IRF7, resulting in the production of proinflammatory cytokines and the induction of an antiviral state (3).

Conjugated Peptide
Anti-TRIM21 antibody was prepared from whole rabbit serum produced by repeated immunizations with an 16 amino acid peptide near the internal region of human TRIM21.
Anti-TRIM21 antibody was affinity purified from monospecific antiserum by immunoaffinity chromatography. TRIM21 antibody is human specific. This antibody is predicted to not cross-react with TRIM6.

Application Details

Anti-TRIM21 Antibody has been tested for use in ELISA, Western Blotting, Immunohistochemistry and Immunofluorescence. Specific conditions for reactivity should be optimized by the end user. Expect a band at approximately 54 kDa in Western Blots of specific cell lysates and tissues.
