    basic FUNCTION
  • ubiquitin-protein isopeptide ligase, required for NF kappa B activation and IL-8 gene expression in response to IL-1, probably through its signal-dependent interaction with IRAK4, IRAK, TRAF6
  • implicated as evolutionary conserved scaffold proteins in TLR/IL-1R signaling leading to nuclear factor-kappaB and mitogen activated protein kinase-dependent gene expression
  • E3 ligases that can catalyze Lys(63)-linked polyubiquitination but also shows bidirectional signaling between the IRAK and Pellino families and highlights a novel function for IRAK kinase activity
  • RING E3 ubiquitin ligases involved in signaling events downstream of the Toll and interleukin-1 (IL1) receptors, key initiators of innate immune and inflammatory responses
  • induce IRAK1 polyubiquitination in a RING-dependent manner
  • PELI1 and PELI2 appear to function as positive regulators for NFKB activation
  • ubiquitin ligase needed for the transmission of TICAM1-dependent TLR signals
  • PELI1, PELI2, PELI3 are novel RING E3 ubiquitin ligases involved in IRAK1 polyubiquitination and degradation
  • PELI2, PELI3 (to a much lesser degree Pellino 1) carry the E3 ubiquitin ligase activity and promote polyubiquitination on IRAK1
  • Pellino1 is a novel component of the signal transduction network by which viral double-stranded RNA stimulates IFNB1 gene transcription
  • PELI1 interacts with the transcription factor DEAF1, and this interaction is independent of the E3 ligase activity of PELI1, but weakened by the phosphorylation of PELI1
  • PELI1, PELI2, PELI3 E3 ubiquitin ligases are emerging as critical mediators for a variety of immune signaling pathways, including those activated by Toll-like receptors, the T-cell receptor, and NOD2
  • nonredundant roles that PELI1, PELI2, PELI3 play in immune signaling are in part due to their divergent substrate specificities
  • promotes lymphomagenesis by deregulating BCL6 polyubiquitination
  • previously unrecognized role of PELI1 in extracellular matrix deposition and cardiac fibroblast activation in response to mechanical stress
  • is an innate immune regulator in the CNS that modulates the threshold of IFN1 responses against viral infections
  • play a pivotal role in inflammatory processes through the activation of Toll-like receptor signaling and the NFKB1 pathway
  • might participate in B-cell maturation or oncogenic activation of aggressive B-cell lymphomas, both during and after germinal center stages
  • PELI1 is a key modulator of RIPK1 that differentially controls the activation of necroptosis and apoptosis
    a component
    small molecule
  • associate with and ubiquitinate proteins, including the interleukin-1 receptor associated kinase-1 (IRAK1)
  • IRAK1-binding region of PELI1, PELI2, PELI3 proteins consists largely of a previously unidentified forkhead-associated (FHA) domain
  • binds constitutively with IL1R and forms an lL1-induced complex with IRAK4-IRAK1-TRAF6
  • targeting of PELI1 by MIR21 could potentially provide the basis for a negative feedback cycle regulating NF-kappaB signaling
  • (IRAK)-interacting proteins that possess RING-like domains
  • IRF3-dependent gene
  • interacting with IKBKE/TBK1 (IKBKE/TBK1 mediate the activation of PELI1 E3 ligase activity, as well as inducing the transcription of its gene and protein expression in response to TLR3 and TLR4 agonists)
  • directly interacted with the oncoprotein B cell chronic lymphocytic leukemia (BCL6) and induced lysine 63-mediated BCL6 polyubiquitination
  • E3 ubiquitin ligase PELI1 is a negative regulator of IFN1 induction in microglia, innate immune cells of the central nervous system (CNS)
  • ubiquitination of RIPK1 by PELI1 promotes the formation of necrosome and execution of necroptosis
  • cell & other
    activated by dephosphorylation of multiple sites (required to inactivate Pellino 1, which could be a device for prolonging Pellino's E3 ubiquitin ligase activity)
