    at STAGE
  • conserved UBC domain of 150AA harboring the cysteine residue required for enzyme-ubiquitin thioester formation
    intraspecies homolog to L-UBC (UBE2L1)
    FAMILY ubiquitin-conjugating enzyme family
    CATEGORY enzyme
    SUBCELLULAR LOCALIZATION     intracellular
    basic FUNCTION
  • ubiquitin dependent proteolytic, mediating the selective degradation of short-lived and abnormal proteins
  • ubiquitin conjugating enzyme mediating c-fos degradation NFKB maturation, human papilloma virus TP53 and MYC degradation in vitro
  • dynamic cell cycle-dependent changes in levels of UBE2L3 regulate entrance into and progression through S phase
  • potential role for its targets in the completion of S phase and entry into G2
  • promotes S phase progression to G2 by modulating the intra-S phase checkpoint mediated by CHEK1
  • reported to function with members of the RING E3 family known as RBRs, which includes parkin and ARIH1
  • exhibits activity with the RING-in-between-RING (RBR) family of E3s that includes PARK2 and ARIH1
  • regulates both the steady-state and replicative stress-induced ubiquitination and proteasome-dependent degradation of the tumor suppressor TP53-binding protein 1 (TP53BP1)
  • important role for UBE2L3 in plasmablast and plasma cell development
  • CELLULAR PROCESS cell cycle
    protein, degradation
    a component
    small molecule
  • UBOX5
  • ARIH1 interacts and co-localizes with UBE2L3 in mammalian cells, particularly in the perinuclear region
  • both UBE2L3 and UBE2L6 bind to RNF19B
  • interaction between the E3 ubiquitin ligase ITCH and the E2 UBE2L3
  • binding UBE3A
  • UBE2N, UBE2L3 and UBE2D2/3 synergistically contribute to PRKN-mediated mitophagy
  • MAP1B-LC1 (light chain) could interact with the ubiquitin-conjugating E2 enzyme UBE2L3 and the ubiquitination/degradation mechanism triggered by MAP1B-LC1 could be prevented by inhibiting the ubiquitin-proteasome proteolytic pathway
  • NDFIP1 acts as an adaptor for UBE2L3 and ITCH
  • controls IL1B secretion by inflammasomes
  • CASP1, controls pyroptosis- and ubiquitin-independent proteasomal degradation of UBE2L3 upon canonical and non-canonical inflammasome activation by sterile danger signals and bacterial infection
  • specifically protects CDKN1B from degradation
  • UBE2L3 catalyzes the conjugation of heterotypic ubiquitin chains on CDKN1B that are proteolytically incompetent

    corresponding disease(s)
  • to Crohn disease
  • to Hashimoto thyroiditis (HT)
  • to systemic lupus erythematosus (SLE)
  • Variant & Polymorphism SNP
  • rs2298428 in UBE2L3 significantly associated with Crohn disease
  • TCGGC haplotype is associated with an increased risk of HT in a Chinese Han population
  • variants carried on the SLE-associated UBE2L3 risk haplotype influence autoimmunity by modulating UBE2L3 expression
