Abstract:
A method of regulating mammalian target-of-rapamycin(mTOR) activity based on mTOR control mechanism by phospholipase D(PLD) AND Rheb(Ras homolog enriched in brain) is provided to cure mTOR-related metabolic disease through the mTOR suppression. A method of regulating mammalian target-of-rapamycin(mTOR) activity comprises (i) coupling Rheb and mTOR through PLD2 by interaction between phospholipase D 2(PLD2) and Rheb; (ii) increasing the concentration of PA by moving phosphatidic acid(PA) produced from PLD2 to adjacent mTOR; and (iii) increasing mTOR kinase activity by coupling Rheb with mTOR through the increase of PA density around the adjacent mTOR.
Abstract:
A method for controlling the activity of mTOR(mammalian target-of-rapamycin) with the interaction of phospholipase D(PLD) and raptor is provided to cure metabolic diseases related with mTOR by controlling mTOR through the control of the PLD activity. A method for controlling the activity of mTOR(mammalian target-of-rapamycin) is to suppress PLD2 through raptor and mTOR complex(PLD/raptor/mTOR complex) by suppressing the interaction of PLD2 and raptor. Suppressing the formation of the PLD/raptor/mTOR complex is performed by inactivating a raptor binding domain of PLD2 or a PLD2 binding domain of raptor.
