The mechanistic target of rapamycin (mTOR) is a serine/threonine kinase that plays a crucial role in regulating cell growth, proliferation, motility, and survival. It is a part of two distinct complexes, mTORC1 and mTORC2, each having unique components and functions. mTORC1 is sensitive to rapamycin, a bacterial macrolide, while mTORC2 is not.
