  • Target

    • Function

      Nuclear hormone receptor. The steroid hormones and their receptors are involved in the regulation of eukaryotic gene expression and affect cellular proliferation and differentiation in target tissues. Can activate the transcriptional activity of TFF1.
    • Sequence similarities

      Belongs to the nuclear hormone receptor family. NR3 subfamily.
      Contains 1 nuclear receptor DNA-binding domain.
    • Domain

      Composed of three domains: a modulating N-terminal domain, a DNA-binding domain and a C-terminal ligand-binding domain.
    • Post-translational

      Phosphorylated by cyclin A/CDK2. Phosphorylation probably enhances transcriptional activity.
      Glycosylated; contains N-acetylglucosamine, probably O-linked.
      Ubiquitinated. Deubiquitinated by OTUB1.
      Dimethylated by PRMT1 at Arg-260. The methylation may favor cytoplasmic localization.
      Palmitoylated (isoform 3). Not biotinylated (isoform 3).
    • Cellular localization

      Nucleus. Cytoplasm. Cell membrane. A minor fraction is associated with the inner membrane and Nucleus. Cytoplasm. Cell membrane. Associated with the inner membrane via palmitoylation.
