  • Function

    Subunit of mTORC2, which regulates cell growth and survival in response to hormonal signals. mTORC2 is activated by growth factors, but, in contrast to mTORC1, 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'. Plays an essential role in embryonic growth and development.
  • Sequence similarities

    Belongs to the RICTOR family.
  • Post-translational

    Phosphorylated by MTOR; when part of mTORC2. Phosphorylated at Thr-1135 by RPS6KB1; phosphorylation of RICTOR inhibits mTORC2 and AKT1 signaling.

Thank you very much for taking the time to complete and send the questionnaire.

The details you have kindly provided will provide us with vital information for our monitoring of product quality.

Unfortunately none of these antibodies have been tested in frozen sections, and therefore they are not guaranteed in this application, nor do we have specific protocols tips to provide for it.

However, there are some suggestions that may optimise the antibody performance, if you wish to give them a try:

-I would recommend decreasing the permeabilization conditions. Both proteins are cytoplasmic; there is no need for such an aggressive permeabilization step. I would repeat the staining skipping this step and removing Triton from the blocking and the washing buffer as well as from the antibody diluent.

-Use milder blocking conditions, using 5% of serum if possible from the same species as the secondary was raised in, to avoid cross reactivity.

-Try using more concentrated dilutions, especially for Raptor antibody (1/50 – 1/25).

If possible I would recommend trying both antibodies in paraffin embedded sections, as they are both guaranteed for it. The link to our protocols page is below, where you can find all the information regarding the different applications protocols, and very useful information for performing paraffin embedded immunostaining.


Should the suggestions not improve the results, please do not hesitate to contact me again and I’ll be more than happy to help you further.

Thank you for contacting us.

I am sorry to hear you are experiencing difficulties with one of our products. We take product complaints very seriously, and investigate every product that we feel may not be performing correctly.

In order to better understand the problem, I would like to send you a questionnaire with some additional questions about the protocol used, as well as the order details. All this information is crucial to help us understand the possible causes of the problem. Any images are highly appreciated.

Once we receive the completed questionnaire, we will look at the protocol and see if there are any suggestions we can make that may improve the results. If no suggestions can be made to the protocol, and the antibody was purchased within the last 6 months, it is covered by our Abpromise guarantee, and therefore I can offer you a free of charge replacement or a credit note for it.

I look forward to receiving your reply. Please do not hesitate to contact us if you need any more advice or information.
