The mammalian target of rapamycin (mTOR), [5] also referred to as the mechanistic target of rapamycin, and sometimes called FK506-binding protein 12-rapamycin-associated protein 1 (FRAP1), is a kinase that in humans is encoded by the MTOR gene. [6] [7] [8] mTOR is a member of the phosphatidylinositol 3-kinase-related kinase family of protein ...
Rapamycin was the first known inhibitor of mTORC1, considering that mTORC1 was discovered as being the target of rapamycin. [83] Rapamycin will bind to cytosolic FKBP12 and act as a scaffold molecule, allowing this protein to dock on the FRB regulatory region (FKBP12-Rapamycin Binding region/domain) on mTORC1. [84]
mTOR inhibitors are a class of drugs used to treat several human diseases, including cancer, autoimmune diseases, and neurodegeneration. They function by inhibiting the mammalian target of rapamycin (mTOR) (also known as the mechanistic target of rapamycin), which is a serine/threonine-specific protein kinase that belongs to the family of phosphatidylinositol-3 kinase (PI3K) related kinases ...
A patient-derived xenograft TNBC model testing the mTOR inhibitor rapamycin showed 77–99% tumor-growth inhibition, which is significantly more than has been seen with doxorubicin; protein phosphorylation studies indicated that constitutive activation of the mTOR pathway decreased with treatment.
Sirolimus is a relatively new medical therapy for the treatment of vascular malformations [25] in recent years, sirolimus has emerged as a new medical treatment option for both vascular tumors and vascular malformations, as a mammalian target of rapamycin (mTOR), capable of integrating signals from the PI3K/AKT pathway to coordinate proper cell ...
Torin_1 is a drug which was one of the first non-rapalog derived inhibitors of the mechanistic target of rapamycin (mTOR) subtypes mTORC1 and mTORC2. [1] [2] ...
Rapamycin-insensitive companion of mTOR , mammalian stress-activated protein kinase interacting protein 1 , and protein observed with rictor 1 and 2 (Protor1/2) can only be found in mTORC2. [ 2 ] [ 3 ] Rictor has been shown to be the scaffold protein for substrate binding to mTORC2.
RPTOR is a 150 kDa mTOR binding protein that is part of the mammalian target of rapamycin complex 1 . This complex contains mTOR, MLST8, RPTOR, AKT1S1/PRAS40, and DEPTOR. mTORC1 both binds to and is inhibited by FKBP12-rapamycin. mTORC1 activity is upregulated by mTOR and MPAK8 by insulin-stimulated phosphorylation at Ser-863.
