mSIN1 protein mediates SGK1 protein interaction with mTORC2 protein complex and is required for selective activation of the epithelial sodium channel.

Abstract excerpt

The mammalian target of rapamycin (mTOR) plays a central role in the regulation of a number of cellular processes including growth, metabolism, and ion transport. mTOR is found in two multiprotein complexes, mTORC1 and mTORC2, which phosphorylate distinct substrates and regulate distinct cellular processes. SGK1 is an mTORC2 substrate, which is a key regulator of epithelial Na(+) transport mediated by the...
