Insulin-like growth factor binding protein 3, also known as IGFBP3, is a protein which in humans is encoded by the IGFBP3 gene.^[1]^[2]

[edit] Function

This gene is a member of the insulin-like growth factor binding protein (IGFBP) family and encodes a protein with an IGFBP domain and a thyroglobulin type-I domain. The protein forms a ternary complex with insulin-like growth factor acid-labile subunit (IGFALS) and either insulin-like growth factor (IGF) I or II. In this form, it circulates in the plasma, prolonging the half-life of IGFs and altering their interaction with cell surface receptors. Alternate transcriptional splice variants, encoding different isoforms, have been characterized.^[2]

[edit] Clinical significance

IGFBP3 protein levels decrease during the progression of prostate cancer from benign prostatic hyperplasia (BPH) to its metastatic form.^[3] Although, production of the protein does not cease completely. IGFBP3 is still made (at a lower level) by prostate cancer cells and secreted into the surrounding environment. However, instead of the full length, functional protein, IGFBP3 is found to be cleaved.^[4] This prevents IGFBP3 from binding and sequestering IGFs and the growth factors are free to bind the IGF-1R and promote cell survival.
