TRAF family member-associated NF-kappa-B activator (TANK)

TRAF family member-associated NF-kappa-B activator (TANK) is a cytoplasmic multifunctional adaptor protein that regulates immune signaling, particularly in pathways leading to the activation or inhibition of NF-kappa-B, a key transcription factor in inflammation, immunity, and cell survival. TANK binds to several TRAF family proteins (TRAF1, TRAF2, TRAF3), often sequestering them and thus inhibiting their downstream signal transduction. It also interacts with TANK-binding kinase 1 (TBK1) and IKBKE, participating in noncanonical NF-kappa-B and antiviral innate immune responses. TANK's activity is context-dependent—it can act both as an inhibitor and coactivator in TRAF-mediated signaling, modulating the activity of TBK1 and the assembly of kinase complexes upstream of NF-kappa-B. Mutations or dysregulation of TANK have been associated with susceptibility to neurological and infectious diseases, and potentially with dysregulated inflammatory states[1][2][3][4].
