CC   -!- FUNCTION: Cooperates with insulin-like peptides to stimulate the
CC       proliferation, polarization and motility of imaginal disk cells. May
CC       act by stabilizing the binding of insulin-like peptides to its receptor
CC       through a simultaneous interaction with both molecules to form a
CC       multiprotein signaling complex (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC   -!- PTM: Glycosylated. {ECO:0000250}.
CC   -!- MISCELLANEOUS: Lacks the typical Glu active site in position 157 that
CC       is replaced by a Lys residue, preventing the hydrolase activity. Its
CC       precise function remains unclear.
CC   -!- SIMILARITY: Belongs to the glycosyl hydrolase 18 family. IDGF
CC       subfamily. {ECO:0000305}.
