Description

General description

IGFBP7 (insulin-like growth factor-binding protein 7) belongs to the IGFBP superfamily and is widely expressed in tissues. It contains 11 cysteines, a heparin binding site, a kazal-type trypsin inhibitor domain and a carboxyl-terminal immunoglobulin-like type C repeat. IGFBP7 binds weakly to IGFs (insulin like growth factors) and strongly to insulin. It mainly participates in IGF-independent pathways. The IGFBP7 gene is mapped to human chromosome 4q12.

SILu^™ Lite IGFBP7 is a recombinant human protein expressed in human 293 cells. It is a protein consisting of 267 amino acids (including an N-terminal polyhistidine tag), with a calculated molecular mass of 28 kDa. SILu Lite IGFBP7 is an analytical standard designed to be used as starting material for preparation of calibrators and controls in LC-MS applications.

Biochem/physiol Actions

IGFBP7 (insulin-like growth factor-binding protein 7) acts as a tumor suppressor as well as an oncogene by controlling cell proliferation, cell attachment, apoptosis and angiogenesis. It is also involved in TGFβ (transforming growth factor beta) signal pathway. IGFBP7 interferes with the insulin pathway and is associated with the development of diabetes as well as cardiovascular diseases.
