Predicted to contribute to guanyl-nucleotide exchange factor activity and molecular adaptor activity. Predicted to be involved in several processes, including negative regulation of cysteine-type endopeptidase activity involved in apoptotic process; positive regulation of interleukin-8 production; and positive regulation of intracellular signal transduction. Predicted to act upstream of or within positive regulation of NF-kappaB transcription factor activity. Predicted to be located in cytosol. Predicted to be part of Ragulator complex. Predicted to be active in lysosome. Orthologous to human LAMTOR5 (late endosomal/lysosomal adaptor, MAPK and MTOR activator 5). [provided by Alliance of Genome Resources, Apr 2022]
