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'.
  • Tissue specificity
    Expressed in numerous tissues, with highest levels in testis.
  • Sequence similarities
    Belongs to the PI3/PI4-kinase family.
    Contains 1 FAT domain.
    Contains 1 FATC domain.
    Contains 7 HEAT repeats.
    Contains 1 PI3K/PI4K domain.
  • Post-translational
    modifications
    Autophosphorylated; when part of mTORC1 or mTORC2.
  • Cellular localization
    Endoplasmic reticulum membrane. Golgi apparatus membrane. Mitochondrion outer membrane. Lysosome. Cytoplasm. Nucleus > PML body. Shuttles between cytoplasm and nucleus. Accumulates in the nucleus in response to hypoxia (By similarity). Targeting to lysosomes depends on amino acid availability and RRAGA and RRAGB.

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!

Can you tell me if it should recognize the following section of the FRAP protein (The rapamycin binding domain): SRILWHEMWHEGLEEASRLYFGERNVKGMFEVLEPLHAMMERGPQTLKETSFNQAYGRDLMEAQEWCRKYMK SGNVKDLLQAWDLYYHVFRRISK

What is the peptide sequence of the antigen used to raise the mTOR antibody : ab2833?

The sequence of the peptide used is proprietary.

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 pr...

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.
