IGF-BPs control the distribution, function and activity of IGFs in various cell tissues and body fluids.  Currently, there are seven named IGF-BPs that form high affinity complexes with both IGF-I and IGF-II.  IGF-BP5 is a 28.6 kDa, cysteine-rich, secreted protein produced by vascular smooth muscle cells.  It is the major IGF-binding protein present in bone tissue and helps potentiate the action of IGF-I on smooth muscle cells, fibroblasts, and osteoblasts.  Data shows that IGFBP-5 acts as a growth inhibitor and pro-apoptotic agent in breast cancer cells.  IGFBP-5-overexpressing mice show an increase in neonatal mortality, reduced female fertility, whole-body growth inhibition, and retarded muscle development.  Recombinant Human IGF-BP5 is a 28.6 kDa protein consisting of 253 amino acid residues.

The ED50 was determined by its ability to inhibit IGF-II induced proliferation of MCF-7 is <= 0.3 µg/ml in the presence of 15 ng/ml of human IGF-II.
