AdipoGen Lipoyl-TRIM21 (human) (rec.) (His) (3 x 10 µg)
Supplier: AdipoGen AG40B01823010
Recombinant protein. Human TRIM21 (aa 1-475) is fused at the N-terminus to a Lipoyl domain (bacterial pyruvate dehydrogenase) and at the C-terminus to a 6xHis-tag. Source/Host: E. coli. Purity: >90% (SDS-PAGE). Lyophilized. Contains 50mM Tris-HCl, pH 8 and 300mM NaCl. 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. 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.
