Predicted to enable several functions, including ATPase inhibitor activity; chaperone binding activity; and guanyl-nucleotide exchange factor activity. Predicted to be involved in several processes, including TOR signaling; positive regulation of TOR signaling; and positive regulation of peptidyl-serine phosphorylation. Predicted to act upstream of or within with a positive effect on negative regulation of cell population proliferation. Predicted to act upstream of or within several processes, including immature B cell differentiation; negative regulation of TOR signaling; and regulation of apoptotic process. Predicted to be located in cytosol and lysosomal membrane. Orthologous to human FNIP1 (folliculin interacting protein 1). [provided by Alliance of Genome Resources, Apr 2022]
