IGFBP3 binds IGF I or IGF II via the conserved N terminus and C terminus of IGFBP 3. IGFBP3 also binds ALS via the C terminal portion of IGFBP3. The interaction is dependent on the glycosylation of ALS.
IGFBP3, which binds most IGF in the body, is enriched in follicular fluid and found in many other tissues. IGFBP3 may be cleaved by plasmin, thrombin, Prostate specific Antigen (PSA, KLK3), Matrix Metalloprotease-1 (MMP1), and Matrix Metalloprotease-2 (MMP2). IGFBP3 also binds extracellular matrix and binding lowers its affinity for IGFs. IGFBP3 stimulates the effects of IGFs.
