靶标

  • 功能
    Acts to integrate nutrient and growth factor signals in regulation of protein synthesis, cell proliferation, cell growth, cell cycle progression and cell survival. Downstream effector of the mTOR signaling pathway. Phosphorylates specifically ribosomal protein S6 in response to insulin or several classes of mitogens. During translation initiation, the inactive form associatess with the eIF-3 complex under conditions of nutrient depletion. Mitogenic stimulation leads to phosphorylation and dissociation from the eIF-3 complex and the free activated form can phosphorylate other translational targets including EIF4B. Promotes protein synthesis by phosphorylating PDCD4 at 'Ser-67' and targeting it for degradation. Phosphorylates RICTOR leading to regulation of mammalian target of rapamycin complex 2 (mTORC2) signaling; probably phosphorylates RICTOR at 'Thr-1135'. Phosphorylates IRS1 at multiple serine residues coupled with insulin resistance; probably phosphorylates IRS1 at 'Ser-270'. Required for TNF-alpha induced IRS-1 degradation. Phosphorylates EEF2K in response to IGF1 and inhibits EEF2K activity. Phosphorylates BAD at 'Ser-99' in response to IGF1 leading to BAD inactivation and inhibition of BAD-induced apoptosis. Phosphorylates mitochondrial RMP leading to dissociation of a RMP:PPP1CC complex; probably phosphorylates RMP at 'Ser-99'. The free mitochondrial PPP1CC can dephosphorylate RPS6KB1 at Thr-412 which is proposed to be a negative feed back mechanism for the RPS6KB1 antiapoptotic function. Phosphorylates GSK3B at 'Ser-9' under conditions leading to loss of the TSC1-TSC2 complex. Phosphorylates POLDIP3.
  • 组织特异性
    Widely expressed.
  • 序列相似性
    Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. S6 kinase subfamily.
    Contains 1 AGC-kinase C-terminal domain.
    Contains 1 protein kinase domain.
  • 结构域
    The autoinhibitory domain is believed to block phosphorylation within the AGC-kinase C-terminal domain and the activation loop.
    The TOS (TOR signaling) motif is essential for activation by mTORC1.
  • 翻译后修饰
    Phosphorylation at Thr-412 is regulated by mTORC1. The phosphorylation at this site is maintained by an agonist-dependent autophosphorylation mechanism.

Answer

Thank you for contacting us.

Yes the customer would be eligible for a testing discount for ab12864 if they are willing to test it in mouse and/or sheep samples with western blotting. The sequence surrounding the Serine 235 and 236 of human RPS6 (SwissProt http://www.uniprot.org/uniprot/P62753), against which the antibody was raised, shares 100% homology with the mouse protein (SwissProt reference http://www.uniprot.org/uniprot/P62754) and we would therefore expect it to react. I was unable to find a sequence for the sheep protein but it seems that the sequence is highly conserved in mammals and I would therefore expect the antibody also to be able to detect the sheep protein.

In order for me to issue a testing discount could you please provide me with the email address and institute that the customer is with.

I look forward to receiving your reply.

Answer

Vielen Dank für Ihre Anfrage und dafür, dass Sie sich die Zeit genommen haben, unseren Fragebogen auszufüllen. Es tut mir leid, dass Sie Probleme mit unserem Antikörper hatten. Ich habe gesehen, dass Sie schon mit meiner Kollegin bezüglich des ab2571 in Kontakt waren. Haben Sie das Problem mit dem ab2571 gelöst? Wir würden uns sehr freuen zu hören, wie Sie vorangekommen sind.

In Bezug auf den ab9366,möchte ich gernedie folgenden Punkte ansprechen und Vorschlägezur Veränderungdes Protokolls machen.

1.) Können Sie bestätigen, dass der sekundäre Antikörper ansonsten gut funktioniert auf diesen Zelllysaten? Gibt der sekundäre Antikörper auch Hintergrundbanden?

2.) Ich kann Ihnen empfehlen, die Zelllysate in einem RIPA Puffer herzustellen. Die Wahl des Puffers ist wichtig, da einige Puffer gewisse Proteine nicht genug gut in Lösung bringen können. RIPA ist ein starker und guter Puffer. In unserem Onlineprotokoll haben wir auch einen Absatz über die Wahl der Puffer: https://www.abcam.com/index.html?pageconfig=resource&rid=11379#A1

3.) Ich kann auch empfehlen, Inhibitoren von Proteasen den Lysaten hinzufügen.

4.) Ich kann auch empfehlen, die Proben zu reduzieren. Falls wir keine spezielle Notiz auf dem Datenblatt haben, wurde der Antikörper unter reduzierten Kondition getestet.

Bitte lassen Sie mich wissen, ob ich Ihnen helfen konnte und zögern Sie nicht, sich wieder bei uns zu melden, falls Sie weitere Fragen haben.

Wie Sie wissen,garantieren wiralle Produkte so zu funktionieren wie auf dem Datenblatt beschrieben. Falls wir also das Problem nicht lösen können, werden wir Ihnen diesen Antikörperersetzen.

Ich freue mich wieder von Ihnen zu hören.

Answer

Thank you for getting back to me.

I understand your concerns over the antibody. I suggested that the antibody may be at fault not because we have had other complaints from customers but because of the optimisation having been performed by the customer and the highly non-specific blot obtained. However, if you have used a further two antibodies to this target with similar results it may be that the samples do not contain the protein as expected. It may be if they have been stored at -80 for a long time, or gone through any freeze thaw cyclesthat they have degraded with time. It may be worthwhile to test the antibodies used with a positive control such as 293T cell lysate or jurkat cell lysate if you have these to hand? If you do not I would be able to provide this for you.

If you would prefer to take a replacement antibody, I can have this organised too. I have had a look at the antibodies suggested against RPS6. Both ab40820 and ab5961 seem like good choices against the unphosphorylated target. These antibodies have both been validated in western blotting and with mouse samples and would therefore both be covered by the Abpromise. From the antibodies chosen against the phosphorylated RPS6target, ab65748 and ab12864, I would suggest ab65748 would be the most appropriate to use as this has been validated with mouse samples which ab12864 has not (we can only say that we would expect it to work due to the sequence homology of the mouse protein with the immunogen used but we cannot guarantee it).

For all of the antibodies suggested, nonehave been used to detect the sheep protein and I cannot therefore say whether they would besuitable for performing western blottingwith thesesamples.

I hope this information has been of help. I look forward to hearing how you would like to proceed.

Answer

Thank you for taking time to complete our questionnaire and for providing me with that extra information. I am sorry that this antibody is not providing satisfactory results.

The details provided will enable us to investigate this case and will provide us with vital information for monitoring product quality. I appreciate the time you have spent in the laboratory and understand your concerns. It is regrettable the results have not been successful.

Having reviewed the protocol details, I believe this product should have given satisfactory results. It appears that you may have received a faulty vial. I apologize for the inconvenience has caused your customer and am pleased to offer you a free of charge replacement, credit note, or refund in compensation. Unfortunately, we only have the same lot of ab9366 in stock at the moment. I would therefore suggest https://www.abcam.com/S6K-antibody-6B2-ab119252.htmlwhich is a mouse monoclonal or https://www.abcam.com/S6K-antibody-ab47504.htmlwhich is a rabbit polyclonal. Both have been validated in WB and with mouse samples.

I would still be veryinterested in seeing the "no primary" control result, just to see if some improvements could be made in improving this non-specificity..

Thank you for your cooperation. I look forward to hearing from you with details of how you would like to proceed.
