TRIM21 (tripartite motif-containing protein 21) is a cytosolic Fc receptor induced by interferon (IFN). TRIM21 is distinguished from other Fc receptors by showing broad antibody specificity as it can activate its functions upon binding to IgG, IgM as well as IgA while other Fc receptors display more restricted antibody isotype and subtype specificities. TRIM21 also functions as a E3 ligase. During infection, antibodies are delivered efficiently to the cytosol when bound to intracellular pathogens such as viruses and bacteria. The antibody-pathogen complex in the cytosol upon engagement of the protein TRIM21 is ubiquitinylated and degraded by the proteasome machinery.  Trim-Away is a method to degrade endogenous proteins based on TRIM21, Fc receptor binding and ubiquitin ligase activity.  TRIM21, which recognizes antibody-bound proteins of interest, targets them for degradation by the proteasome. The Lipoyl-TRIM21 (human) (His) (rec.) protein is used in the original papers describing Trim-Away.
