IHC-P Use at an assay dependent concentration.


  • FunctionNuclear 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 similaritiesBelongs to the nuclear hormone receptor family. NR3 subfamily.
    Contains 1 nuclear receptor DNA-binding domain.
  • DomainComposed 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 localizationNucleus. Cytoplasm. Cell membrane. A minor fraction is associated with the inner membrane and Nucleus. Cytoplasm. Cell membrane. Associated with the inner membrane via palmitoylation.
