Enables GTP binding activity. Predicted to be involved in several processes, including cellular response to amino acid starvation; negative regulation of autophagy; and positive regulation of TORC1 signaling. Predicted to be located in cytoplasm. Predicted to be part of Gtr1-Gtr2 GTPase complex. Predicted to be active in lysosome and nucleus. Orthologous to human RRAGA (Ras related GTP binding A).
