A method is provided of decreasing or increasing the activity of a Pappalysin polypeptide by decreasing or increasing the level of interacting Pappalysin and stanniocalcin polypeptides. A method is also provided of preventing, treating or ameliorating a clinical condition in a mammalian subject, such as a human being, said method comprising administering to said mammalian subject, such as human being an effective amount of a stanniocalcin polypeptide. Moreover, a method is provided of preventing, treating or ameliorating a clinical condition in a mammalian subject, such as a human being, said method comprising administering to said mammalian subject, such as human being an effective amount of an agent capable of antagonizing interaction of a stanniocalcin polypeptide with a Pappalysin polypeptide.

The present disclosure relates to antigen binding proteins. More particularly the present disclosure relates to pregnancy associated plasma protein-A (PAPPA) binding proteins, even more particularly PAPPA binding proteins that inhibit cleavage of insulin like growth factor binding protein-2 (IGFBP-2), insulin like growth factor binding protein-4 (IGFBP-4) and insulin like growth factor binding protein-5 (IGFBP-5). The present disclosure further relates to the use of said binding proteins in medicine.
