產品描述：

Recombinant protein corresponding to 49-118aa from the human insulin-like growth factor I (IGF1) was expressed in E.coli. This recombinant IGF1 protein was fused with a GST-tag at the N-terminus. It has high purity (>90%) as measured by SDS-PAGE and a predicted molecular weight of 34.7 kDa. In-stock IGF1 proteins are offered now. In addition to the production of specific antibodies, this recombinant IGF1 protein may be used in the studies of IGF1-related signal transduction.

IGF1 is a pleiotropic hormone involved in various physiological functions. For instance, IGF-1 exerts a relevant role in fetal development, growth during childhood and adolescence, and adult tissue homeostasis. It has been demonstrated that IGF1 has cardioprotective, neural protective, and insulin-like effects and modulates skeletal metabolism and muscle regeneration. On the other hand, IGF1 promotes certain tumor cell proliferation by regulating the cell cycle, apoptosis, and cell survival via the IGF-1/PI3K/AKT/mTOR pathway.

功能：

The insulin-like growth factors, isolated from plasma, are structurally and functionally related to insulin but have a much higher growth-promoting activity. May be a physiological regulator of [1-14C]-2-deoxy-D-glucose (2DG) transport and glycogen synthesis in osteoblasts. Stimulates glucose transport in bone-derived osteoblastic (PyMS) cells and is effective at much lower concentrations than insulin, not only regarding glycogen and DNA synthesis but also with regard to enhancing glucose uptake. May play a role in synapse maturation. Ca(2+)-dependent exocytosis of IGF1 is required for sensory perception of smell in the olfactory bulb. Acts as a ligand for IGF1R. Binds to the alpha subunit of IGF1R, leading to the activation of the intrinsic tyrosine kinase activity which autophosphorylates tyrosine residues in the beta subunit thus initiatiating a cascade of down-stream signaling events leading to activation of the PI3K-AKT/PKB and the Ras-MAPK pathways. Binds to integrins ITGAV:ITGB3 and ITGA6:ITGB4. Its binding to integrins and subsequent ternary complex formation with integrins and IGFR1 are essential for IGF1 signaling. Induces the phosphorylation and activation of IGFR1, MAPK3/ERK1, MAPK1/ERK2 and AKT1.
