  • 由来種

    Mouse

  • 特異性

    Immunocytochemical staining of GR in L929 cells with this antibody results in staining of both the cytoplasm and nucleus, even in the presence of hormone. This antibody, using enzymatic digestion analysis, has been shown to react with the undigested 97 kDa GR, a 17 kDa DNA-binding trypsin fragment, and a 45 kDa steroid- and DNA-binding chymotrypsin fragment.

ターゲット情報

  • 機能

    Receptor for glucocorticoids (GC). Has a dual mode of action: as a transcription factor that binds to glucocorticoid response elements (GRE) and as a modulator of other transcription factors. Affects inflammatory responses, cellular proliferation and differentiation in target tissues. Could act as a coactivator for STAT5-dependent transcription upon growth hormone (GH) stimulation and could reveal an essential role of hepatic GR in the control of body growth. Involved in chromatin remodeling. Plays a significant role in transactivation. Involved in nuclear translocation.

  • 組織特異性

    Widely expressed. In the heart, detected in left and right atria, left and right ventricles, aorta, apex, intraventricular septum, and atrioventricular node as well as whole adult and fetal heart.

  • 関連疾患

    Defects in NR3C1 are a cause of glucocorticoid resistance (GCRES) [MIM:138040]; also known as cortisol resistance. It is a hypertensive, hyperandrogenic disorder characterized by increased serum cortisol concentrations. Inheritance is autosomal dominant.

  • 配列類似性

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

  • ドメイン

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

  • 翻訳後修飾

    Increased proteasome-mediated degradation in response to glucocorticoids.
    Phosphorylated in the absence of hormone; becomes hyperphosphorylated in the presence of glucocorticoid. The Ser-203-phosphorylated form is mainly cytoplasmic, and the Ser-211-phosphorylated form is nuclear. Transcriptional activity correlates with the amount of phosphorylation at Ser-211.
    Sumoylated; this reduces transcription transactivation.
    Ubiquitinated; restricts glucocorticoid-mediated transcriptional signaling.

  • 細胞内局在

    Cytoplasm. Nucleus. Cytoplasmic in the absence of ligand, nuclear after ligand-binding and Nucleus. Localized largely in the nucleus.

    Question

    I'm having trouble with the mentioned antibody. I am running immunohistochemistry with fixed free-floating brain tissue with DAB. I tried my protocol with antigen-retrieval using citrate buffer and heat, and without retrieval steps. The concentration of antibody used was 1:500. Nothing is staining at all.

    Question

    Phone call requesting information of the epitope recognised by the anti-Glucocorticoid Receptor antibody [BuGR2] (ab2768).

    Read More
    Answer

    Thank you for contacting us yesterday and sorry for the delay in getting back to you.

    I can now share with you the information we have in regards to the epitope recognised by the Anti-Glucocorticoid Receptor antibody [BuGR2] (ab2768).

    The epitope recognised by the antibody has been determined to be within the region 407 to 422 or Rat Glucocorticoid Receptor (SwissProt reference http://www.uniprot.org/uniprot/P06536). This corresponds to the region 388-402 of the human Glucocorticoid Receptor (SwissProt reference P04150). I would therefore expect the antibody to detect both the alpha and beta forms of the receptor. However, as we have not performed any studies to determine this conclusively I would not be able to guarantee this.

    I hope this information has been of help. If you have any further questions, please do not hesitate to ask.

    Answer

    Thank you for your enquiry regarding ab2768 and for taking the time to provide some useful details of the experiments. I am very sorry to hear that you are having problems with this antibody.

    After reading through the detailed protocol you kindly forwarded to Abcam, I would like to make the following comments/suggestions:

    1) Isoforms:

    According to the literature, 9 different isoforms have been described :http://www.uniprot.org/uniprot/P04150 and it is possible that the customer may detect some splice variants.

    2) Lysis buffer:

    Could you please specify the compositions of the lysis buffer? Does it contain detergent?

    3) Loading:

    Has the customer tried to load less total protein than 30 ug per lane i.e. 5-10 ug.

    4) Blocking:

    Longer blocking than 30 mins would be recommended for this case such as 1 hour.

    5) Positive control:

    It would be worth running a positive control along with the samples such as liver or kidney tissue lysate (from mouse or human). As the on-line Western blot image indicates, total mouse liver lysate was used to test this antibody in the Lab.

    I hope this will be useful for you. Should you still have any problem with this antibody after following these suggestions, then please do not hesitate to contact our Technical Department again.
