Background: A20/TNFAIP3
A20/TNFAIP3 is a highly conserved protein sharing >90% amino acid sequence identity across various mammalian species and is highly expressed in T-cell and B-cells. Coding and non-coding single nucleotide polymorphisms (SNPs) of A20/TNFAIP3 have been associated with multiple autoinflammatory and autoimmune diseases including type 1 diabetes, rheumatoid arthritis, Crohn's disease, and systemic lupus erythematosus (SLE) (3). The two domains of A20/TNFAIP3 cooperate to regulate NF-kB signaling. Its N-terminal ovarian tumor (OTU) domain contains a catalytic cysteine (C103) which functions as a K63 deubiquitinase, whereas the 7 zinc fingers that make up the C-terminal domain mediate K48 polyubiquitination. To regulate NF-kB signaling, A20/TNFAIP3 removes K63-polyubiquitin chains from receptor-interacting protein 1 (RIP1) and NF-kB essential modulator (NEMO), thus preventing interactions with downstream partners. A20/TNFAIP3 also contributes to the degradation of RIP1 and Ubc13 through the addition of K48 polyubiquitin chains (4).

FAQs for A20/TNFAIP3 Antibody - BSA Free
-
Q: Following cleavage of A20/TNFAIP3, two full length fragments are released, one with 37 kDa and other one was approx. at 52 kDa. There are mentioning of 75Kda fragment and 37 KDa fragment in scientific papers but not 52 KDa. What is the significance of that specific band?
A: There is data available that explains 52 KDa band in A20/TNFAIP3. Using this antibody in Western Blot will result multiple bands. In LPS treatment, 52 KDa putative cleavage band was observed; however, the same band was not found in untreated THP1 cells.
