    basic FUNCTION
  • RNA helicase with RNA dependent ATPase activity
  • DEAH-box RNA-dependent ATPase that catalyzes the release of excised lariat intron from the mRNA spliceosome
  • putative ATP-dependent RNA helicase implicated in pre-mRNA splicing
  • in cooperation with TFIP11 mediates the transition from the intron large complex to the intron small complex, leading to efficient debranching and turnover of excised introns (Yoshimoto 2009)
  • DHX15 activates NFKB1 and MAPK signaling downstream of MAVS during antiviral responses
  • is a new RNA virus sensor mediated by MAVS to activate the immune responses to RNA
  • CELLULAR PROCESS nucleotide, RNA splicing
    text preRNA splicing
    a component
    small molecule
  • interacting with SSB (may be colocalized in the nucleoli)
  • interacting with TFIP11 (protein component of the spliceosome complex that promotes the release of the lariat-intron during late-stage splicing through a direct recruitment and interaction with DHX15) (Tannukit 2009)
  • DHX15 and PRPF19, two spliceosome components, are novel RBM5-interacting partner
  • DHX15 physically interacted with MAVS and mediated the MAVS-dependent activation of the NFKB1 and MAPK pathways
  • NLRP6 functions with DHX15 as a viral RNA sensor to induce IFN-stimulated genes (ISGs), and this effect is especially important in the intestinal tract
  • NKRF mediates the recruitment of the exonuclease XRN2 and activation of the RNA helicase DHX15 in human ribosome biogenesis
  • DHX15 regulates AR activity by modulating E3 ligase SIAH2-mediated AR ubiquitination independent of its ATPase activity
