Abstract
The Rag GTPases appear to reside on the lysosome and link amino acid stimulation to mTOR complex 1 (mTORC1) activation. mTORC1 couples nutrient availability to cell growth. Dysregulation of mTORC1 is implicated in a number of human diseases, including cancer and diabetes. In response to amino acid availability the Rag GTPases are regulated by the Ragulator and GATOR complexes, which are a guanine nucleotide exchange factor (GEF) and GTPase activating protein (GAP), respectively. Here we review the current knowledge of Rag GTPases, with emphasis on amino acid-dependent regulation of mTORC1.
