== Function Summary ==
* **Entrez Summary**: N/A
* **UniProt Summary**: Functions as an intracellular arginine sensor within the amino acid-sensing branch of the TORC1 signaling pathway. As a homodimer or a heterodimer with CASTOR2, binds and inhibits the GATOR subcomplex GATOR2 and thereby mTORC1. Binding of arginine to CASTOR1 allosterically disrupts the interaction of CASTOR1- containing dimers with GATOR2 which can in turn activate mTORC1 and the TORC1 signaling pathway. {ECO:0000269|PubMed:26972053, ECO:0000269|PubMed:27487210}.
