生化/生理作用
Human IGFBP-3 is the major insulin-like growth factor (IGF) binding protein in plasma, where it exists in a ternary complex with IGF-I or IGF-II and the acid-labile subunit (ALS).
IGFBPs (insulin like growth factor binding proteins) regulate bioavailability of IGFs (insulin like growth factors) in cells. Binding between IGFs and IGFBPs reduces the availability of the IGFs. However, IGFBPs also concentrate IGFs in specific areas to potentiate their effects at right time. IGFBP3 binds to IGF-1. It is a tumor suppressor and is downregulated in many cancers. In serum, IGFs, IGFBP3 and the acid labile subunit (ALS) exist together as a complex. This complex is important for increasing the half life of serum IGFs.
外形
Lyophilized from a 0.2 μm filtered solution in 30% acetonitrile and 0.1% TFA.
分析说明

Nuclear factor-kappaB (NF-κB) is a transcription factor that is activated in various neoplasms, including gastric cancer. Insulin-like growth factor binding protein-3 (IGFBP-3) is a potent tumor suppressor and is significantly suppressed in a variety of cancers. Although IGFBP-3 has been

Previous studies have demonstrated the polymorphisms of insulinlike growth factor-1 (IGF-1) and its binding protein-3 (IGFBP3) genes could affect the circulating IGF-1 level. Moreover, the serum IGF-1 level was correlated with muscle size. This study aimed to explore the effect

IGF-1 is a growth-promoting polypeptide that is essential for normal growth and development. In serum, the majority of the IGFs exist in a 150-kDa complex including the IGF molecule, IGF binding protein 3 (IGFBP-3), and the acid labile subunit (ALS).

Insulin-like growth factor binding protein-3 (IGFBP-3) can modulate the mitogenic and metabolic effects of the insulin-like growth factors (IGFs). IGFBP-3 protein levels are developmentally regulated and influenced by a number of hormonal stimuli both in vitro and in vivo. As
