Automated description from the Alliance of Genome Resources
Predicted to have arginine binding activity and identical protein binding activity. Predicted to be involved in cellular response to L-arginine and negative regulation of TORC1 signaling. Predicted to colocalize with the GATOR2 complex. Is expressed in thymus primordium and vibrissa. Orthologous to human CASTOR1 (cytosolic arginine sensor for mTORC1 subunit 1).
