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).
