    at STAGE
  • N terminal acidic domain
  • two NR box domain with specific LXXLL sequence motif, a short hydrophobic domain that is sufficient for ligand-dependent interactions with nuclear receptors
  • two glutamine-rich domains
  • an intrinsic glutamine-rich activation domain
  • multiple functional modules including pleckstrin homology and C2 domains, inhibited exocytosis, probably via the binding to membrane phosphoinositides through the pleckstrin homology domain
  • C-terminal domain is required for the interaction with SMAD2, and SMAD3

    basic FUNCTION
  • coactivator of PPARG and RXR alpha (potentiates the transcriptional activities)
  • playing a critical role as a coactivator of nuclear receptors
  • coactivator of the xenobiotic nuclear receptor NR1I3 and mediate the specific xenobiotic response by NR1I3
  • coactivator of multiple nuclear receptors and transcription factors
  • with MLL3, NCOA6 and MLL4 are recruited to FXR target genes in a ligand-dependent manner
  • co-activator for nuclear hormone receptors and certain other transcription factors
  • plays an important role in embryonic development, adipocyte differentiation, metabolism and breast carcinogenesis
  • controls E(2) sensitivity and uterine receptivity by regulating multiple E(2)-signaling components
  • has an inhibitory role in regulated exocytosis
  • is a transcriptional coactivator and crucial for insulin secretion and glucose metabolism in pancreatic beta-cells
  • NCOA6 stimulates insulin secretion likely, at least partially, by modulating NAMPT expression in pancreatic beta-cells
  • CELLULAR PROCESS nucleotide, transcription
    text transcriptional activator
    signaling hormonal
    a component
  • component of a steady-state complex (ASCOM) also containing retinoblastoma binding protein RBQ3, alpha/beta tubulins and a subset of trithorax group proteins
    small molecule
  • thyroid hormone receptor binding
  • peroxisome proliferation-activated receptor interacting protein
  • interacting with ATF2 to induce target gene transcription during granulocytic differentiation
  • interacting with ZNF335
  • binds to many nuclear receptors in a ligand-dependent manner through its two LxxLL motifs
  • differentially regulates CYP2C9 and CYP3A4 gene expression though both the genes are regulated by the same nuclear receptors
  • reported coactivator for ESR1, attenuates E(2) sensitivity to determine uterine receptivity to embryo implantation under normal physiological conditions

  • PRIP-deficient mice showed increased serum gonadotropins, but decreased gonadal steroid hormones
  • Prip gene knock-out (KO) in mice increases bone formation and concomitantly decreases bone resorption, resulting in increased bone mineral density and trabecular bone volume
