    text a fraction of endogenous and ectopically expressed TNFAIP3 is localized to an endocytic membrane compartment that is in association with the lysosome
    basic FUNCTION
  • inhibiting NF-kappa B activation as well as TNF-mediated apoptosis
  • critical for limiting inflammation by terminating TNF-induced NF-kappa B responses
  • may be involvement of a lysosome-associated mechanism in TNFAIP3-dependent termination of NFkappaB signaling
  • playing a role in the function of the lymphoid system
  • contribute to the in vivo effects of TNF
  • inhibitor of NF-kB signaling that may play an important role in lymphomagenesis
  • having a function in the regulation of CARD10 and BCL10 activity in lymphoid and non-lymphoid cells
  • ubiquitin modifying enzyme that restricts NF-kappaB signals and protects cells against tumor necrosis factor (TNF)-induced programmed cell death
  • plays a key role in the negative regulation of inflammation and immunity
  • negatively regulates NFkappaB (nuclear factor kappaB) signaling induced by TNF receptor family and Toll-like receptors
  • negatively regulates TRAF3-stimulated IRF7 ubiquitination and activity in Epstein-Barr virus latency, and its deubiquitinase activity is indispensable for this function
  • tightly regulates NFKB signaling by acting as an Ub editor
  • involved in the negative feedback regulation of NFKB signaling in response to specific proinflammatory stimuli in different cell types
  • TNIP1 cooperates with TAX1BP1 and TNFAIP3 to restrict antiviral signaling
  • plays a critical role in the termination of NFKB signaling after activation
    • CELLULAR PROCESS cell life, antiapoptosis

  • binding to NAF1, TRAF1 and TRAF2
  • binding to TAX1BP1 (functioning as a negative regulator of ubiquitination of key signaling molecules that are also targeted by TNFAIP3)
  • TNIP1 requires its ubiquitin binding domain and cooperates with TAX1BP1 and TNFAIP3 to restrict antiviral signaling
