Predicted to enable sterol esterase activity. Acts upstream of or within several processes, including homeostasis of number of cells within a tissue; lung development; and tissue remodeling. Predicted to be located in cytosol; lysosome; and nuclear lumen. Predicted to be active in intracellular membrane-bounded organelle. Is expressed in several structures, including adrenal cortex zone; alimentary system; brain; hemolymphoid system; and metanephros. Used to study Wolman disease and lysosomal and lipase deficiency. Human ortholog(s) of this gene implicated in Wolman disease; cholesterol ester storage disease; and lysosomal and lipase deficiency. Orthologous to human LIPA (lipase A, lysosomal acid type).
