    basic FUNCTION
  • play an important role in hormone-responsive tissues and cancer
  • play a pivotal role in hormone-stimulated breast cancer growth
  • may be critically involved in prostate cancer proliferation
  • unexpected role for GREB1 as an estrogen-specific ESR1 cofactor that is expressed in drug-sensitive contexts

    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • in breast cancer cells, NR5A2 promotes cell proliferation by enhancing ESR1 mediated transcription of target genes such as GREB1
  • Il6/STAT3 modulates estrogen-induced GREB1 transcriptional activity in breast cancer cells
  • is a chromatin-bound ESR1 coactivator and is essential for ESR1-mediated transcription, because it stabilizes interactions between ESR1 and additional cofactors
