IGFBP 1 binds IGF I or IGF II via the conserved N terminus and C terminus of IGFBP 1. IGFBP 1 is enriched in amniotic fluid and is produced in the liver under control of insulin (insulin suppresses production). IGFBP 1 acts to stimulate IGF function. It is unknown which if any protease degrades IGFBP 1.
