title: Raptor swoops in on metabolism.
abstract: The mammalian target of rapamycin (mTOR) serine/threonine kinase plays a central role in insulin signaling and cell growth, through two distinct complexes with its subunits raptor or rictor. In this issue, two reports utilizing tissue-specific knockout mice detail key roles for mTORC1 in skeletal muscle and adipose tissue function.
