  • with CALCOCO2 and myosin VI are present at the trans side of the Golgi complex, and on vesicles in the perinuclear region(Morriswood 2007)
  • basic FUNCTION
  • inhibiting TNF-induced apoptosis by mediating the TNFAIP3 anti-apoptotic activity
  • may also play a role in the pro-inflammatory cytokine IL-1 signaling cascade
  • playing a pivotal role for the termination of NFKB and JNK signaling by functioning as an essential regulator of TNFAIP3
  • nuclear receptor coactivator that forms a complex with the glucocorticoid receptor
  • inhibit NF-kappaB activation, and is implicated in the regulation of TRAF6-mediated cytokine signalling (Morriswood 2007)
  • together with TAX1BP1 and ITCH, is an essential component of an TNFAIP3 ubiquitin-editing protein complex that ensures transient activation of inflammatory signalling pathways (Shembade 2009)
  • functions as an adaptor molecule for TNFAIP3 and together they target TBK1 and IKKBE to inhibit IFNB production
  • pivotal for the termination of NF-kappaB and JNK signaling by functioning as an essential regulator of TNFAIP3 (Shembade 2009)
  • TNIP1 cooperates with TAX1BP1 and TNFAIP3 to restrict antiviral signaling
  • pleiotropic protein that plays many essential functions in human cells, including negative regulation of inflammatory and antimicrobial responses mediated by NFKB1 and IRF3 signaling, inhibition of apoptosis, transcriptional coactivation and autophagy
  • TAX1BP1 restricts ERK activation and PRDM1 expression and regulates germinal center formation
  • TAX1BP1 drives a specialized form of autophagy, providing critical amino acids that activate MTOR and enable the metabolic transition of activated T cells

  • interacting with TRAF6 in a IL-1-dependent manner (interaction between the N-terminal zinc and ring finger domains of TRAF6 and either the N-terminal first coiled-coil region or the 2 coiled-coil regions of the C-terminus of TAX1BP1)
  • interacting with TNFAIP3 (functioning as a negative regulator of ubiquitination of key signaling molecules that are also targeted by TNFAIP3)
  • interacting with STARD13
  • interacting with the HTLV-1 protein Tax-1
  • interactig with CNTN2
  • myosin VI binding partner (myosin VI-TAX1BP1 interactions may link membrane trafficking pathways with cell adhesion and cytokine-dependent cell signalling)(Morriswood 2007)
  • interacts cooperatively with OPTN (OPTN and TAX1BP1 cooperate to modulate Tax1 ubiquitination and NF-kappaB activation)(Journo 2009)
  • key regulator of TNFAIP3 function in terminating signaling to IRF3
  • TNIP1 requires its ubiquitin binding domain and cooperates with TAX1BP1 and TNFAIP3 to restrict antiviral signaling
  • TBK1 kinase addiction in lung cancer cells is mediated via autophagy of TAX1BP1/CALCOCO2 and non-canonical NFKB1 signalling
  • ubiquitin-binding protein that restricts nuclear factor-kappaB (NFKB1) activation and facilitates the termination of aberrant inflammation
  • TAX1BP1 functions as an adaptor molecule for ITCH to target MAVS during RNA virus infection and thus restrict virus-induced apoptosis
