The mammalian target of rapamycin (mTOR) is a protein kinase that controls cellular metabolism, catabolism, immune responses, autophagy, survival, proliferation, and migration, to maintain homeostasis. mTOR signaling cascade consists two distinct multi-subunit complexes named complex 1/2 (mTORC1/2). catalyzes the phosphorylation several critical proteins like AKT, C, insulin growth factor receptor (IGF-1R), 4E binding 1 (4E-BP1), ribosomal S6 (S6K), transcription EB (TFEB), sterol-responsive element-binding (SREBPs), Lipin-1, Unc-51-like autophagy-activating kinases. plays central role in regulating translation, lipid synthesis, nucleotide biogenesis lysosomes, nutrient sensing, signaling. emerging pieces evidence have revealed constitutive activation pathway due mutations/amplification/deletion either its (mTORC1 mTORC2) or upstream targets responsible for aging, neurological diseases, human malignancies.
