The mammalian target of rapamycin complex 1 (mTORC1) activity is paramount in the regulation of electrical activities in the brain and the heart. In the brain, the tumor suppressor gene TSC2 encodes the protein product tuberin that interacts with hamartin to form a heterodimer Tuberous Sclerosis Complex (TSC) that regulates mTORC1. When TSC2 is disrupted, mTORC1 activity becomes dysregulated resulting in abnormal electrical activities in the brain manifesting in the form of epileptic seizures. In the heart, mTORC1 activity is triggered by a sustained increase in hemodynamic pressure causing the heart to electrically remodel. A likely candidate serving as the …
