  • two RNA-binding (RNA recognition motif [RRM]) domains
  • unique regions rich in glutamine, histidine, arginine and glutamine acid
  • a NOPS domain, characteristic of DBHS proteins, specifically binding to RRM2 of the partner DBHS protein
  • a protein phosphatase 1 (PP1) consensus binding RVXF motifs, playing an important role in controlling the multifunctional properties of NONO and SFPQ in the regulation of gene transcription
  • C-terminal coiled-coil motif essential for paraspeckle localization
  • mono polymer heteromer , dimer , tetramer
    interspecies homolog to Drosophila NONA/BJ6

  • DBHS (Drosophila melanogaster behavior, human splicing) family
  • CATEGORY RNA associated
    SUBCELLULAR LOCALIZATION     intracellular
    intracellular,nucleus,nucleoplasm,nuclear bodies,nuclear speckles
  • predominately nuclear
  • in interphase cells, localizes to the nucleoplasm and concentrates with protein partners in the paraspeckles via an interaction with the non-coding RNA NEAT1
  • basic FUNCTION
  • functioning as a coactivator of androgen receptors that potentiates transcription and possibly splicing
  • with PSPC1 and SFPQ, may cooperatively regulate androgen receptor-mediated gene transcription
  • plays an important role in the regulation of Sox9 function and the formation of paraspeckle bodies during chondrogenesis
  • acting as a bridge between the CREB/TORC complex and RNA polymerase II (Amelio 2007)
  • having a functions in recruitment of XRN2 to facilitate pre-mRNA 3' processing and transcription termination (Kaneko 2007)
  • core paraspeckle proteins
  • SFPQ/NONO heterodimer was previously found to enhance DNA strand break rejoining
  • critical to the control of gene expression through the nuclear retention of RNA containing double-stranded RNA regions that have been subject to adenosine-to-inosine editing
  • involved in many nuclear processes including transcription, RNA processing, and retention of hyperedited RNAs
  • involvement of NONO and SFPQ in DNA double-strand break repair (DSB) and radioresistance
  • serve as transcriptional cofactor for correct circadian clock function, where it regulate the circadian clock via interaction with PER proteins
  • important role of NONO, PSPC1, SFPQ within the circadian oscillator
  • overlapping or redundant roles of NONO, PSPC1, SFPQ as transcriptional cofactors at circadian clock-regulated genes
  • regulates synaptic transcription and gephyrin scaffold structure
  • may likely contribute to the regulation of RNA metabolism underlying local regulation of dendritic spine morphology and has a major and unsuspected role in regulating synaptic morphology at a cellular level
  • CELLULAR PROCESS nucleotide, RNA splicing
    a component
  • heterotetramer of two 52kDa and two 100kDa subunits
  • SFPQ/NONO heterodimer
  • PSPC1/NONO heterodimer has a right-handed antiparallel coiled-coil that positions two of four RNA recognition motif domains in an unprecedented arrangement
  • interaction with RNA could be selectively modulated by phosphorylation during mitosis
  • small molecule
  • interacting with SOCS3 (SOCS3 acts as a suppressor by regulating the action of NONO)
  • interacting with FAM123B
  • interacting with PARK7 and SFPQ (binding partner in dopaminergic neuronal cells)
  • HNRNPM interacts with SFPQ and NONO and co-localizes within defined nuclear structures
  • SFPQ interacts directly with RAD51 and deficiency of both proteins confers a severe loss of cell viability, indicating a synthetic lethal relationship
  • GJA1 is a downstream target molecule of NONO
  • partner of circadian PERIOD (PER) proteins
  • bound to the CDKN2A cycle checkpoint gene and potentiated its circadian activation in a PER protein-dependent fashion
  • is essential for glucocorticoids-mediated expression of occludin, CLDN5, and barrier induction, and the NONO/SFPQ heterodimer may contribute to normal blood-retinal barrier (BRB) induction
  • although NONO and SFPQ are nuclear paraspeckle components, these proteins formed cytoplasmic granules with RBPMS in the neurites
  • cooperative function of HNRNPM and NONO as regulators of internal ribosome entry site (IRES)-dependent translation, indicating the involvement of a promoter-dependent mechanism
