Analysis Note

The biological activity is measured by its ability to inhibit recombinant human lGF-II on MCF-7 cells.

Biochem/physiol Actions

IGFBP-2 (insulin-like growth factor binding protein-2) regulates the function of IGF ligands. IGFBP2 is associated with skeletal muscle cell proliferation and differentiation. It also plays an important role in the differentiation of corneal fibroblast.

During development, insulin-like growth factor binding protein-2 is expressed in a number of tissues with the highest expression level found in the central nervous system. IGFBP-2 exhibits a 2-10 fold higher affinity for IGF II than for IGF I. Mouse and human IGFBP-2 share approximately 82% homology.

General description

The gene IGFBP-2 (insulin-like growth factor binding protein-2) is mapped to human chromosome 2q35.
