Antibody Type: Polyclonal
Antibody Host Species: Rabbit
Antibody Immunogen Source: Human mTOR (FRAP) sequence peptide Cat. No.: PE-01ARD80
Antibody Immunogen Sequence: FNQAYGRDLMEAQEWC
Antibody Immunogen Description: Corresponds to amino acid residues F2070 to C2085.
Production Method: The immunizing peptide was produced by solid phase synthesis on a multipep peptide synthesizer and purified by reverse-phase hplc chromatography. Purity was assessed by analytical hplc and the amino acid sequence confirmed by mass spectrometry analysis. This peptide was coupled to KLH prior to immunization into rabbits. New Zealand White rabbits were subcutaneously injected with KLH-coupled immunizing peptide every 4 weeks for 4 months. The sera from these animals was applied onto an agarose column to which the immunogen peptide was thio-linked. Antibody was eluted from the column with 0.1 M glycine, pH 2.5. Subsequently, the antibody solution was neutralized to pH 7.0 with saturated Tris.
Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Scientific Background: mTOR (FRAP1) is a 289 kDa protein-serine/threonine kinase of the Atypical group and PIKK family. It mediates cell growth, proliferation, metabolism, and survival. It senses nutrient, energy, and growth factor levels to balance cell metabolism. mTOR exists in two distinct complexes, mTORC1 (growth/protein synthesis) and mTORC2 (cytoskeleton/survival). mTORC1 integrates signals from growth factors like insulin, energy status (via AMPK), and amino acids (leucine, arginine) to regulate protein synthesis and inhibit autophagy. mTORC2 regulates the actin cytoskeleton, cell polarity and migration, and metabolism, including Akt/PKB phosphorylation. It targets eIF4e and p70S6 kinase activation for protein synthesis. Phosphorylation of Ser-2448 and Ser-2481 increases its phosphotransferase activity, and it is stimulated by RHEBm. Phosphorylation of Thr-2446 inhibits phosphorylation of the Ser-2448 activatory site. It is also negatively regulated by DEPDC6. mTOR has several functional domains: FAT Domain (Amino acids 1382-1982); PI3K/PI4K Catalytic Domain (Amino acids 2156-2469); FATC Domain (Amino acids 2517-2549); an interaction region for binding to FKBP1A/rapamycin (Amino acids 2012-2144); and an NBN interaction region (Amino acids 1-651). Dysregulation in signalling that leads to constant activation of mTOR lead to uncontrolled proliferation and cell cycle progression and oncogensis. Increased invasiveness has also be shown to be associated with mTOR activity. While it features a wide range of mutations, this might reflect the very large size of the protein rather than its identification as a tumour suppressor protein. Cancer-related mutations for mTOR in human tumours point to a gain of function of the protein kinase, indicating that it might function as an oncoprotein (OP). The active form of the protein kinase normally acts to promote tumour cell proliferation. Defective mTOR signalling has been linked with diabetes, Tuberous Sclerosis, Subependymal Giant Cell Astrocytoma (SEGA), Lymphangioleiomyomatosis (LAM), Tuberous Sclerosis Complex, Plasmablastic Lymphoma (PBL), Ewing's tumours, and Kidney Angiomyolipoma. Rapamycin and its analogs (rapalogs) inhibit mTOR, and are useful in cancer treatment. This description may include information annotated by UniProt and/or Google AI.
