  • N-terminal "domain present in ubiquitin specific proteases" (DUSP)
  • five highly conserved domains, domain I, II and III containing the expected catalytic triad Cys, Asp, His which defines cysteine proteases
  • "ubiquitin-like" (UBL) domains (DU subfamily)
    interspecies ortholog to Usp15, Rattus norvegicus
    ortholog to Usp15, Mus musculus
    ortholog to USP15, Pan troglodytes

    SUBCELLULAR LOCALIZATION     intracellular
    basic FUNCTION
  • acting as an ubiquitin specific protease
  • play a critical role in dorsoventral patterning through the BMP pathway
  • involved in the regulation of hypertrophic responses in cardiac muscle through transcriptional and post-translational modulation of FHL1
  • functions in COP9 signalosome mediated regulation of protein degradation and cellular signaling through catalyzing the ubiquitin deconjugation reaction of a discrete number of substrates
  • required for TGFB1 and BMP responses in mammalian cells
  • critical for the occupancy of endogenous target promoters by the SMAD complex
  • a key component of the TGF-beta signaling pathway, and in glioblastoma pathogenesis as well
  • USP4 and USP15 extend the life of activated receptors against the negative pressure of receptor-ubiquitinating complexes, but through distinct modes of action
  • a key regulator of cellular RE1-silencing transcription factor, REST
  • specifically deubiquitinates Keap1
  • CELLULAR PROCESS protein, ubiquitin dependent proteolysis
    metabolism protein
  • Ubl conjugation pathway
  • a component
    small molecule
  • COP9 signalosome (CSN) protein complex
  • HPV16 E6
  • skeletal muscle LIM protein 1, LIM1
  • E3 ligase BRAP
  • Tsc22d3
  • specifically deubiquitinates KEAP1, which suppresses the NFE2L2 pathway
  • USP15 interacted with RORC, removed ubiquitin from K446, and stimulated RORC activity by enhancing coactivator SRC recruitment (positive role for USP15-mediated deubiquitination of RORC in Th17 differentiation)

    Variant & Polymorphism
    Candidate gene
  • may be a candidate diagnostic marker and therapeutic target for Paclitaxel-resistant cancers
  • Therapy target
  • lack of USP15 causes Paclitaxel resistance
  • USP15-siRNA enhances chemoresistance of cells through upregulation of Nrf2
