Phospholipase D-Dependent Mtorc1 Activation By Glutamine, Elyssa Bernfeld
Phospholipase D-Dependent Mtorc1 Activation By Glutamine, Elyssa Bernfeld
Dissertations, Theses, and Capstone Projects
Glutamine, the conditionally essential amino acid and most abundant amino acid in human sera, is a key nutrient required for sustaining cell proliferation. Glutamine is essential for nucleotide, protein, and lipid synthesis, all of which are essential for cell proliferation. The mammalian target of rapamycin complex 1 (mTORC1) is a highly conserved protein complex that acts as a sensor of nutrients, relaying signals for the shift from catabolic to anabolic metabolism. While glutamine plays an important role in activating mTORC1, the mechanism is not completely clear. Here we describe a Rag-independent mechanism of mTORC1 activation by glutamine that is dependent …
Characterization Of A Variant Of Tuberous Sclerosis Complex 2 And Its Interaction With Rheb, Sowmya Sivakumar
Characterization Of A Variant Of Tuberous Sclerosis Complex 2 And Its Interaction With Rheb, Sowmya Sivakumar
Graduate Theses and Dissertations
Protein-protein interactions are vital in maintaining proper function and homeostasis in cells. Some signaling pathways are regulated by G-proteins that work like switches to activate and deactivate pathways. Mutations in these proteins, their effectors or the interaction between proteins may cause dysregulation of signals that can lead to many diseases.
Rheb, Ras homology enriched in brain, is a Ras family GTPase that is vital in regulation of the mTOR (mammalian target of rapamycin) pathway that signals cell proliferation and growth. Due to the low intrinsic GTPase activity of Rheb, a GTPase activating protein (GAP), Tuberous Sclerosis Complex 2 (TSC2) down …
