    text
  • a portion localizes in nuclear speckle domains, and its efficient recruitment to mRNA is both splicing- and cap-dependent
  • basic FUNCTION
  • cytokine regulated protein involved in normal and cancer cell proliferation
  • up-regulated in response to various cytokines
  • may play a role in cell cycle progression
  • enhancing RNA unwinding activity of DDX39
  • may participate in important transcriptional or translational control of cell growth, metabolism and carcinogenesis
  • function in splicing, export, or translation, as it binds RNA and interacts with BAT1
  • functions in mRNA export
  • CELLULAR PROCESS cell life, proliferation/growth
    nucleotide, transcription, regulation
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component SARNP, THOC4, and BAT1 form an ATP-dependent trimeric complex, and BAT1 bridges the interaction between SARNP and THOC4
    INTERACTION
    DNA
  • specifically binding to scafflod/matrix attachement region DNA
  • binding both double-stranded and ss DNA
  • RNA binding to ssRNA
    small molecule
    protein
  • interacting with FUS
  • binding BAT1 and DDX39
  • with THOC4, associate with TREX in an ATP-dependent manner, and BAT1 mediates the association between these proteins and the THO complex to form TREX
