Predicted to enable GTP binding activity and GTPase activity. Predicted to be involved in cellular response to starvation; negative regulation of autophagy; and positive regulation of TORC1 signaling. Predicted to be located in cytoplasm and membrane. Predicted to be part of Gtr1-Gtr2 GTPase complex. Predicted to be active in lysosome and nucleus. Is expressed in heart. Used to study cardiomyopathy. Orthologous to human RRAGC (Ras related GTP binding C).
