mTOR: dissecting regulation and mechanism of action to understand human disease

mTOR (mammalian target Of rapamycin) is a highly conserved serine/threonine Protein kinase that has roles in cell metabolism, cell growth and cell survival. Although it has been known for some years that mTOR acts as a hub for inputs from growth factors (in particular insulin and insulin-like growth factors), nutrients and cellular stresses, some of the mechanisms involved are still poorly understood. Recent work has implicated mTOR in a variety of important human pathologies, including cancer, Type 2 diabetes and neurodegenerative disorders, heightening interest and accelerating progress in dissecting out the control and functions of mTOR.
