Function

FUNCTION: Ubiquitin-editing enzyme that contains both ubiquitin ligase and deubiquitinase activities. Involved in immune and inflammatory responses signaled by cytokines, such as TNF-alpha and IL-1 beta, or pathogens via Toll-like receptors (TLRs) through terminating NF-kappa-B activity. Essential component of a ubiquitin-editing protein complex, comprising also RNF11, ITCH and TAX1BP1, that ensures the transient nature of inflammatory signaling pathways. In cooperation with TAX1BP1 promotes disassembly of E2-E3 ubiquitin protein ligase complexes in IL-1R and TNFR-1 pathways; affected are at least E3 ligases TRAF6, TRAF2 and BIRC2, and E2 ubiquitin-conjugating enzymes UBE2N and UBE2D3. In cooperation with TAX1BP1 promotes ubiquitination of UBE2N and proteasomal degradation of UBE2N and UBE2D3. Upon TNF stimulation, deubiquitinates 'Lys-63'-polyubiquitin chains on RIPK1 and catalyzes the formation of 'Lys-48'-polyubiquitin chains. This leads to RIPK1 proteasomal degradation and consequently termination of the TNF- or LPS-mediated activation of NF-kappa-B. Deubiquitinates TRAF6 probably acting on 'Lys-63'-linked polyubiquitin. Upon T-cell receptor (TCR)-mediated T-cell activation, deubiquitinates 'Lys-63'-polyubiquitin chains on MALT1 thereby mediating disassociation of the CBM (CARD11:BCL10:MALT1) and IKK complexes and preventing sustained IKK activation. Deubiquitinates NEMO/IKBKG; the function is facilitated by TNIP1 and leads to inhibition of NF-kappa-B activation. Upon stimulation by bacterial peptidoglycans, probably deubiquitinates RIPK2. Can also inhibit I-kappa-B-kinase (IKK) through a non-catalytic mechanism which involves polyubiquitin; polyubiquitin promotes association with IKBKG and prevents IKK MAP3K7-mediated phosphorylation. Targets TRAF2 for lysosomal degradation. In vitro able to deubiquitinate 'Lys-11'-, 'Lys-48'- and 'Lys-63' polyubiquitin chains. Inhibitor of programmed cell death. Has a role in the function of the lymphoid system. Required for LPS- induced production of proinflammatory cytokines and IFN beta in LPS-tolerized macrophages. {ECO:0000269|PubMed:14748687, ECO:0000269|PubMed:15258597, ECO:0000269|PubMed:16684768, ECO:0000269|PubMed:17961127, ECO:0000269|PubMed:18164316, ECO:0000269|PubMed:18952128, ECO:0000269|PubMed:19494296, ECO:0000269|PubMed:22099304, ECO:0000269|PubMed:23827681, ECO:0000269|PubMed:8692885, ECO:0000269|PubMed:9299557, ECO:0000269|PubMed:9882303}.;

Disease

DISEASE: Autoinflammatory syndrome, familial, Behcet-like (AISBL) [MIM:616744]: An autosomal dominant, autoinflammatory disorder with early onset, characterized by ulceration of mucosal surfaces, particularly in the oral and genital areas. Additional variable features include skin rash, uveitis, and polyarthritis. {ECO:0000269|PubMed:26642243, ECO:0000269|PubMed:27175295}.
