  • General notes

    Western blot protocol advice:

    Since intracellular levels of pS294 ER are very low, Western blot without prior immunoprecipitation of total ER is not sensitive enough to detect pS294 ER. We recommend initial ER immunoprecipitation, following which it is possible to use this antibody for Western blot (see data image).

  • 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.

  • MCF7 cells growing in phenol red-free medium supplemented with 5% charcoal stripped serum for 24 hours were treated for 25 minutes with vehicle (C = control), 10nM E2, or pretreated for 20 minutes with 1uM Dinaciclib (CDK2 inhibitor) and then 25 minutes with E2 treatment (Din/E2). Harvested cells were lysed and immunoprecipitated using an ERα N-terminal directed rabbit polyclonal antibody; and the immunoprecipitated ERα (45 ml final volume each from C, E2 and Din/E2 samples) was used to prepare separate western blots probed with either ab207602 anti-ERpS294 monoclonal, or antibodies specific for ERpS118 or total ERα, all of which run at 67 kDa molecular weight.

    Alternatively, cell lysates can first be immunoprecipitated with ab207602 anti-ERpS294 monoclonal and the immunoprecipitate then western blotted with other antibodies specific for ERα (not shown).
