Target

  • Function

    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'.

Answer

Thank you and your customer for your inquiry.

I believe that the images that your customers provided do show very nice specific staining.

According to the Uniprot homepage (http://www.uniprot.org/uniprot/P42345) mTOR is expressed in the endoplasmic reticulum membrane, the Golgi apparatus membrane, the mitochondrion outer membrane, theLysosome and the Cytoplasm. It shuttles between cytoplasm and nucleus.

If it is in the nucleus, it is located in thePML bodies which is nicely shown by your customers image.

I am happy to confirm that this antibody does not seem to exhibit any un-specific staining and that your customers results are very nice.

I hope I could reassure your customer that their results are specific. Please let me know if your customer has any other questions.

Question

Dear Abcam technical support

I'm interested to buy an antibody against mTOR which works well in Western blot.

According to NCBI the molecular weight of mTOR is 289kDa.
The antibodies against mTOR you are selling i.e. ab2732 show specificity against a protein of 255kDa.

I was wondering where this difference is coming from?

And which of the antibodies against mTOR would you advice me to buy for use in Western blot?

Many thanks

Answer

Thank you for contacting us and your interest in our products.

When trying to detect a protein of the size of mTOR in Western blotting, there is some movement of the band that would be expected away from the predicted band size. Due to how the ladder and protein runs in the SDS-PAGE gel there can be quite large variations in proteins of this size so the size of 255 kDa observed with ab2732 would not be unexpected. The antibody has been used in the staining of HepG2 cells as well as rat testis, supporting it detecting the expected protein.

I have had a look through the antibodies we have against this target and I would suggest also taking a look at the mouse monoclonal ab87540 which has been used in Western blotting and produced a clean band of ˜268 kDa with HEK293 and human liver tissue (amongst other samples).

However, I'd like to reassure you that both the ab2732 and ab87540 would be covered by the Abpromise guarantee if you intend to use it in Western blotting with human samples. More information on this guarantee can be found from the following link:

https://www.abcam.com/abpromise

I'd also like to draw your attention to our protocol booklet which has some useful advice when performing Western blotting with such large proteins. This booklet can be accessed from the following link:

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