Predicted to enable dynein light intermediate chain binding activity and small GTPase binding activity. Predicted to be involved in several processes, including early endosome to late endosome transport; intralumenal vesicle formation; and regulation of protein catabolic process. Predicted to act upstream of or within protein transport. Located in mitochondrion. Part of protein-containing complex. Is expressed in brown fat; ileum; liver; male reproductive gland or organ; and metanephros. Orthologous to human RILP (Rab interacting lysosomal protein).
