    at STAGE
  • an N-terminal kinase domain similar to that found in RIPK1, RIPK2, and RIPK4 , followed by an RHIM domain, through which it interacts with RIPK1 , and a Ser/Thr kinase domains (KDs)
  • a unique homotypic interaction motif at the C terminus of both RIPK1 and RIPK3 that is required for their association
  • protein kinase superfamily
  • TKL Ser/Thr protein kinase family
  • CATEGORY regulatory
    SUBCELLULAR LOCALIZATION     plasma membrane
    basic FUNCTION
  • crucial modulator of epidermal differentiation, and important and unique functions in keratinocytes of normal and wounded skin
  • crucial activator for programmed necrosis induced by TNF and during virus infection
  • regulates necrosis-specific RIPK1 phosphorylation
  • controls programmed necrosis by initiating the pronecrotic kinase cascade, and this is necessary for the inflammatory response against virus infections
  • By activating key enzymes of metabolic pathways, RIP3 regulates TNF-induced reactive oxygen species production, which partially accounts for RIP3 ability to promote necrosis
  • RIPK1 and RIPK3 are key signaling molecules in necrosis and are regulated by caspases and ubiquitination
  • key signaling molecule in the programmed necrosis (necroptosis) pathway
  • RIPK1, RIPK3 are central players in TNF-induced programmed necrosis
  • participates in caspase-8 activation by acting downstream of the cytosolic death complex assembly, possibly via reactive oxygen species generation
  • critical regulator of programmed necrosis/necroptosis, an inflammatory form of cell death with important functions in pathogen-induced and sterile inflammation
  • necroptosis is controlled by the action of two serine/threonine kinases, RIPK1 and RIPK3
  • is an essential upstream kinase in necroptosis
  • RIPK1 and RIPK3 directly regulate inflammatory signaling, which complicates interpretation of their function but might alter their therapeutic utility
    a component
  • pronecrotic RIPK1-RIPK3 complex is induced during vaccinia virus infection
  • 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 and RIPK3 play a critical role in mediating progressive axonal degeneration
    small molecule
  • binds RIPK1 through its unique C-terminal segment to inhibit RIP- and TNF receptor-1-mediated NF-kappaB activation
  • ZBP1 recruits RIPK1 and RIPK3 through RIP homotypic interaction motifs to activate NF-kappaB
  • BIRC2, BIRC3 are direct E3 ubiquitin ligases for all four RIP proteins and that BIRC2 is capable of conjugating the RIPs with diverse types of ubiquitin chains, including linear chains
  • 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
  • CASP8 control of death receptor and TLR necrotic death signaling depends on basal catalytic activity that suppresses the RIPK3 kinase pathway
  • pseudokinase MLKL functions as a substrate of RIPK3 to mediate downstream signaling
  • MLKL is a key RIPK3 downstream component of tumour necrosis factor (TNF)-induced necroptosis
  • RIPK1 blocks early postnatal lethality mediated by CASP8 and RIPK3
  • XIAP controls RIPK3-dependent cell death and IL1B secretion in response to TNF, which might contribute to hyperinflammation in patients with XLP2
  • RIPK1 intrinsically suppresses spontaneous RIPK3 activation in the cytosol by controlling RIPK3 oligomerization
  • RIPK1 regulates hematopoiesis and prevents inflammation by suppressing RIPK3 activation
  • RIPK3 is an unexpected positive regulator of CASP8 activity that promotes IL1B maturation in bone marrow-derived dendritic cells (BMDCs)
  • HSP90AA1 and CDC37 cochaperone complex-mediated protein folding is thus an important part of the RIPK3 activation process during necroptosis.
  • PGAM5 is a mitochondrial phosphatase that has been reported to function downstream of RIPK3 to promote necroptosis and IL1B secretion
  • RHIM motif of RIPK1 is critical for preventing ZBP1/RIPK3/MLKL-dependent necroptosis during development
  • RIPK3 interacts with MAVS to regulate type I IFN-mediated immunity to Influenza A virus infection
  • unexpected roles for RIPK1 and RIPK3 kinases in the production of IFNB1 during the host inflammatory responses to bacterial infection, suggesting that the axis in which these kinases operate may represent a target for bacterial virulence factors
