    basic FUNCTION
  • dual-function molecule that can be either prosurvival or prodeath depending on its ubiquitination state, and this serves as an NF-kappaB-independent cell-death switch early in TNF signaling
  • playing an important role for DNA damage-induced, TP53-independent cell death
  • one of the critical components involved in mediating DNA damage-induced, TP53-independent cell death
  • one of the major components of the tumor necrosis factor receptor 1 complex and plays an essential role in tumor necrosis factor-mediated nuclear factor kappaB activation (
  • plays a critical role in tumor necrosis factor-alpha (TNF)-induced IkappaB kinase (IKK) activation and subsequent activation of transcription factor NF-kappaB
  • inhibiting the expression of the epidermal growth factor receptor (EGFR)
  • crucial modulator of epidermal differentiation, and important and unique functions in keratinocytes of normal and wounded skin
  • specifically recruited to the TNFalpha receptor in the activation of necroptosis
  • critical mediator of inflammation and stress-induced NF-kappaB activation, regulates the expression of the epidermal growth factor receptor (EGFR)
  • downregulates EGFR expression by interfering with the function of Sp1, which is a key activator of EGFR transcription
  • required for death receptor agonists to activate necrosis
  • RIPK1 and RIPK3 are key signaling molecules in necrosis and are regulated by caspases and ubiquitination
  • required for CD40 ligand-induced caspase-8 activation and tumor cell killing
  • RIPK1 and caspase-8 were recruited to the DDX58 complex after viral infection and served antagonistic regulatory roles
  • regulates embryogenesis and lymphocyte responses (
  • a IKBKG- and RIPK1-based switch mechanism involving TNF-TNFR1 feedforward signaling that mediates ATM-induced cytokine secretion and caspase activation selectively in the context of severe DNA damage
  • is a central kinase in TNFR1 signaling participating in NFKB activation, necroptosis, and apoptosis
  • functions as a platform mediating survival signals and as an active kinase during necroptosis and apoptosis in the presence of Smac mimetics
  • RIPK1, RIPK3 are central players in TNF-induced programmed necrosis
  • key switch of cell fate regulation
  • CELLULAR PROCESS cell life, cell death/apoptosis
    signaling signal transduction
    interacting with IKBKG and modulatory NF-kappa B activation and apoptosis

  • CD40 (
  • interacting with ATM (in the context of excessive DNA damage, ATM employs IKBKG and RIPK1 through autocrine TNF signaling to switch on cytokine production and caspase activation)
  • FCMR regulates the balance between apoptotic and nonapoptotic death receptor signaling by facilitating RIPK1 ubiquitination
  • PGAM5 is a kinase substrate of RIPK1/RIPK3
  • necroptosis depends on the kinases RIPK1 and RIPK3, which interact through their RHIM domains to form the necrosome
  • recruitment of IKBKG to ubiquitinated RIPK1 is a key step in the TNFR1 signaling pathway that determines whether RIPK1 triggers a necrotic death response
