DESCRIPTION

Also known as TANK_HUMAN, TANK, ITRAF, TRAF2. Adapter protein involved in I-kappa-B-kinase (IKK) regulation which constitutively binds TBK1 and IKBKE playing a role in antiviral innate immunity. Acts as a regulator of TRAF function by maintaining them in a latent state. Blocks TRAF2 binding to LMP1 and inhibits LMP1-mediated NF-kappa-B activation. Negatively regulates NF-kappaB signaling and cell survival upon DNA damage (PubMed:25861989). Plays a role as an adapter to assemble ZC3H12A, USP10 in a deubiquitination complex which plays a negative feedback response to attenuate NF-kappaB activation through the deubiquitination of IKBKG or TRAF6 in response to interleukin-1-beta (IL1B) stimulation or upon DNA damage (PubMed:25861989). Promotes UBP10-induced deubiquitination of TRAF6 in response to DNA damage (PubMed:25861989). May control negatively TRAF2-mediated NF-kappa-B activation signaled by CD40, TNFR1 and TNFR2. Homodimer. Found in a deubiquitination complex with TANK, USP10 and ZC3H12A; this complex inhibits genotoxic stress- or interleukin-1-beta-mediated NF-kappaB activation by promoting IKBKG or TRAF6 deubiquitination (PubMed:25861989). Interacts with IKBKG; this interaction increases in response to DNA damage (PubMed:25861989). Interacts with TRAF6; this interaction increases in response to DNA damage and recruits USP10 to the ubiquitinated TRAF6 (PubMed:25861989). Interacts with USP10; this interaction increases in response to DNA damage (PubMed:25861989). Interacts with ZC3H12A; this interaction increases in response to DNA damage (PubMed:25861989). Interacts with TBK1 (PubMed:10581243, PubMed:21931631, PubMed:29251827). Interacts with IKBKE (PubMed:17568778). Interacts also with TRAF1, TRAF2, and TRAF3 by binding to their TRAF-C domains; the interaction with TRAF2 is disrupted by the phosphorylation of TANK by IKBKE (PubMed:10759890, PubMed:12005438). Interacts more strongly with TRAF1 and TRAF2 than TRAF3 (PubMed:10759890, PubMed:12005438). Interacts with IKBKG; the interaction is enhanced by IKBKE and TBK1 (PubMed:12133833). Part of a ternary complex consisting of TANK, IKBKB and IKBKG (PubMed:12133833).
