  • 機能
    SOCS family proteins form part of a classical negative feedback system that regulates cytokine signal transduction. SOCS3 is involved in negative regulation of cytokines that signal through the JAK/STAT pathway. Inhibits cytokine signal transduction by binding to tyrosine kinase receptors including gp130, LIF, erythropoietin, insulin, IL12, GCSF and leptin receptors. Binding to JAK2 inhibits its kinase activity. Suppresses fetal liver erythropoiesis. Regulates onset and maintenance of allergic responses mediated by T-helper type 2 cells. Regulates IL-6 signaling in vivo (By similarity). Probable substrate recognition component of a SCF-like ECS (Elongin BC-CUL2/5-SOCS-box protein) E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Seems to recognize IL6ST.
  • 組織特異性
    Widely expressed with high expression in heart, placenta, skeletal muscle, peripheral blood leukocytes, fetal and adult lung, and fetal liver and kidney. Lower levels in thymus.
  • パスウェイ
    Protein modification; protein ubiquitination.
  • 関連疾患
    Note=There is some evidence that SOCS3 may be a susceptibility gene for atopic dermatitis linked to 17q25. SOCS3 messenger RNA is significantly more highly expressed in skin from patients with atopic dermatitis than in skin from healthy controls. Furthermore, a genetic association between atopic dermatitis and a haplotype in the SOCS3 gene has been found in two independent groups of patients.
  • 配列類似性
    Contains 1 SH2 domain.
    Contains 1 SOCS box domain.
  • ドメイン
    The ESS and SH2 domains are required for JAK phosphotyrosine binding. Further interaction with the KIR domain is necessary for signal and kinase inhibition.
    The SOCS box domain mediates the interaction with the Elongin BC complex, an adapter module in different E3 ubiquitin ligase complexes.
  • 翻訳後修飾
    Phosphorylated on tyrosine residues after stimulation by the cytokines, IL-2, EPO or IGF1.

  • Localization of ab3693 as the precipitated red signal, with a hematoxylin purple nuclear counterstain in cardiac myocytes.

  • Predicted band size : 27 kDa
    A431 whole cell lysate was probed with rabbit anti-SOCS-3 ab3693 at 1:200 dilution. A431 whole cell lysate was probed with rabbit anti-SOCS-3 (ab3693) at 1:200 dilution.
  • ab3693 (2µg/ml) staining SOCS3 in human jejunum using an automated system (DAKO Autostainer Plus). Using this protocol there is staining of the cells within the lamina propria.
    Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffers EDTA pH 9.0 in a DAKO PT link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako envision flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that, for manual staining, optimization of primary antibody concentration and incubation time is recommended. Signal amplification may be required.

In general it would be ideal to have a positive control as perhaps SOCS3 is not expressed in A549 cells. We have another antibody go SOCS3, ab16030, where the antibody shows detection of a band in a number of common tumor cell types, Hela, Jurkat,...

You mentioned using another antibody to SOCS3 which did not produce the thick band at 37kDa. Did that antibody produce a band just at 27kDa?

Thanks for your email.

It was a good idea to use the "EasyBlocker" reagent. It makes it quite clear that there is no SOCS3 being pulled down (IP'd) using ab3693, although the antibody does function well for western blotting al...

Thanks so much for providing the additional details. I just have a few more follow up questions:

3. Based on the included WB image, it seems SOCS3 is detected from the input via WB but not the IP/WB. Do you agree? NO
==>If you could, ...

Thank you for your enquiry and for including a western blot image. I just have a few additional questions:

1. This seems to be an IP/WB experiment. Is this the case?

2. Is ab3693 used for both IP and WB? If not, which antibodies are...

Thank you for your reply.

I was wandering if the fellow who ordered the product would be able to provide some of the original order information? As I mentioned in my previous emails, I am willing to extend the 6 month Abpromise for a few mont...

Thank you for your reply.

I understand your situation, but I do need to have some indication about when ab3693 was actually ordered. A date, name or PO number would work.

As I mentioned previously, I am willing to extend the Abpromi...
