靶标

  • 功能

    Kinase subunit of both mTORC1 and mTORC2, which regulates cell growth and survival in response to nutrient and hormonal signals. mTORC1 is activated in response to growth factors or amino-acids. Growth factor-stimulated mTORC1 activation involves AKT1-mediated phosphorylation of TSC1-TSC2, which leads to the activation of the RHEB GTPase that potently activates the protein kinase activity of mTORC1. Amino-acid-signaling to mTORC1 requires its relocalization to the lysosomes mediated by the Ragulator complex and the Rag GTPases. Activated mTORC1 up-regulates protein synthesis by phosphorylating key regulators of mRNA translation and ribosome synthesis. mTORC1 phosphorylates EIF4EBP1 and releases it from inhibiting the elongation initiation factor 4E (eiF4E). mTORC1 phosphorylates and activates S6K1 at 'Thr-421', which then promotes protein synthesis by phosphorylating PDCD4 and targeting it for degradation. Phosphorylates MAF1 leading to attenuation of its RNA polymerase III-repressive function. mTORC2 is also activated by growth. factors, but seems to be nutrient-insensitive. mTORC2 seems to function upstream of Rho GTPases to regulate the actin cytoskeleton, probably by activating one or more Rho-type guanine nucleotide exchange factors. mTORC2 promotes the serum-induced formation of stress-fibers or F-actin. mTORC2 plays a critical role in AKT1 'Ser-473' phosphorylation, which may facilitate the phosphorylation of the activation loop of AKT1 on 'Thr-308' by PDK1 which is a prerequisite for full activation. mTORC2 regulates the phosphorylation of SGK1 at 'Ser-422'. mTORC2 also modulates the phosphorylation of PRKCA on 'Ser-657'.

Question

I am looking for an mTOR antibody produced from an immunogen peptide with close homology to the honey bee TOR homolog. For some of your relevant antibodies the exact sequence is not provided. Could you please send me the immunogen peptide sequence for: ab2833: Synthetic peptide (Human) which represents a portion of human Mammalian Target of Rapamycin encoded in part by exons 5 and 6. ab25880: Synthetic 15 amino acid peptide from the amino terminus of human TOR Thanks so much for your help. I hope one of your antibodies will be a good match.

Answer

Thank you for your enquiry. Unfortunately the immunogen sequences for both ab2833 and ab25880 are proprietary. I can however tell you that with regards ab25880; based on an alignment with NCBI accession number XP_625130 [**- *:* * ***: ] the honey bee shows a degree of similarity making it possible that this antibody will cross-react with its homolog. The immunogen sequence for ab2833 is disimilar to fruit fly or mosquito and therefore is unlikely to cross react with honey bee. I hope this information helps, please do not hesitate to contact us if you need any more advice or information.

Question

Thank you for your email! We loaded 20 µg as instructed by the specification sheet of the lysate but you are right in pointing out that indeed 50 µg was loaded when using the ab 2833 antibody (we are using both ab 2833 and 2732). Although I am uncertain whether we have 50 µg left of the lysate (50µg is half of what was supplied!) we will load the remaining lysate on the next gel; I have serious doubts that it will make difference however since there was no band at the correct mol weight region.... We are working with the placenta and we have obtained single strong, distinct bands at 230-240 kDa in both human and rat placenta. If we were able to verify that this band indeed is mTOR I believe that our gels may be something for your specification sheet in the future. A positive control (liver lysate) would have been a little help however access to the antigenic peptide would be better. Are there antigenic peptides available for ab 2833 and 2732? Our preliminary data on mTOR in the placenta and in various pregnancy complications has made us quite excited and I will order some related products (1093 and 5454) tonight

Answer

Thank you for your email. How did the lysate work out for you? I'm glad to hear that you are getting results with your experimental samples but know how important it is to verify what the band is!

Question

One of the antibodies we have recently purchased from you is anti- mTOR ab2833 which, according to the data sheet, has been tested successfully in western blot. We have a long experience using Western; however so far we have not been able to produce a 235 kDa band shown in your data sheet, instead we obtain a prominent band at half that size. We have so far only used denaturating conditions so my question is whether the 235 kDa band in your data sheet was obtained under denaturating or non-denaturating conditions?? Any other ideas to optimize the western with this particular antibody?

Read More
Answer

Yes, denaturing conditions were used when this antibody was tested in WB. Consider using a lower percentage gel and long transfer times at low voltage to assure transfer of mTor.
