Predicted to contribute to guanyl-nucleotide exchange factor activity and molecular adaptor activity. Predicted to be involved in several processes, including cellular response to amino acid stimulus; positive regulation of TOR signaling; and regulation of cell growth. Predicted to act upstream of or within several processes, including fibroblast migration; positive regulation of MAPK cascade; and regulation of cell-substrate junction organization. Predicted to be located in late endosome. Predicted to be part of Ragulator complex. Orthologous to human LAMTOR2 (late endosomal/lysosomal adaptor, MAPK and MTOR activator 2).
