Pregnancy-associated plasma protein-A2 (PAPP-A2) is a protease of IGFBP-5.
Deletion of Pappa2 increased circulating IGFBP-5 and IGF-I and decreased IGFBP-3.
Deletion of Pappa2 did not affect fasting glucose levels or glucose tolerance.
Deletion of Pappa2 had no effect on adiposity on a high-fat diet.
