  • present both in the cytoplasm and in the nucleus
  • SIRT2 and RIPK1 are identified in the cytotrophoblast cytoplasm
    • 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
  • 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
  • specifically recruited to the TNFalpha receptor in the activation of necroptosis
  • 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
  • necroptosis is controlled by the action of two serine/threonine kinases, RIPK1 and RIPK3
  • RIPK1 can activate RIPK3 in response to receptor signaling, but also acts as a negative regulator of spontaneous RIPK3 activation in the cytosol
  • is essential for survival of intestinal epithelial cells (IECs), ensuring epithelial homeostasis by protecting the epithelium from CASP8-mediated IEC apoptosis independently of its kinase activity and NFKB1 activation
  • RIPK1 is dispensable for necroptosis and can act as an inhibitor of this process
  • key player in inflammation and cell death, that assumes opposite functions depending on the cellular context and its posttranslational modifications
  • is essential for the regulation of death receptor mediated autophagy and apoptosis
  • RIPK1 and RIPK3 directly regulate inflammatory signaling, which complicates interpretation of their function but might alter their therapeutic utility
  • RIPK1 and RIPK3 play a critical role in mediating progressive axonal degeneration
  • RIPK1 regulates cell death and inflammation through kinase-dependent and -independent functions
  • inhibits apoptosis and necroptosis through kinase-independent functions, which are important for late embryonic development and the prevention of inflammation in epithelial barriers
  • enzyme acting downstream of tumor necrosis factor alpha to control cell survival and death
    • CELLULAR PROCESS cell life, cell death/apoptosis
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling signal transduction
  • interacting with IKBKG and modulatory NF-kappa B activation and apoptosis
  • necroptosis is a RIPK1-dependent programmed cell death (PCD) pathway that is distinct from apoptosis
    • a component
  • RIPK1 and RIPK3 form an amyloid structure through their RHIMs and that this heterodimeric amyloid structure is a functional signaling complex that mediates programmed necrosis
  • RIPK1 also formed a complex with VDR, and RIPK1 increased VDR retention in the cytoplasm, which may account for its inhibition of VDR transcriptional activity

  • 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
  • AKT1 activity, mediated in part through MTOR, links RIPK1 to JNK activation and autocrine production of TNF
  • likely TNF-induced necroptosis is tightly associated with oxidative stress, and oxidative stress is induced downstream of RIPK1 activation
  • PELI3 targets RIPK1, in a TNF-dependent manner, to inhibit TNF-induced complex II formation
  • intrinsically suppresses spontaneous RIPK3 activation in the cytosol by controlling RIPK3 oligomerization
  • regulates hematopoiesis and prevents inflammation by suppressing RIPK3 activation
  • indirectly regulates likely CASP8 activation, in part via interaction with the ER stress sensor inositol-requiring protein 1 (ERN1)
