Sujet: IGF-II is a member of the IGF family that is comprised of three members (IGF-I, IGF-II, and insulin). IGF-I and IGF-II share approximately 50 % similarity with insulin at the amino acid level. IGF-II is synthesized as a 180 amino acid in the pro-IGF-II form, pro-IGF-II is processed to the mature, active protein with the help of glucose regulating protein 94 (GRP94) that possesses chaperone activity towards IGF-II. GRP94 and IGF-II play a key role in muscle differentiation. Seven binding proteins have been described (IGFBP-1 to -7). IGFBPs extend the half life and regulate the availability of the IGFI and IGFII. It has been described that IGFBP3 is the main circulating binding protein for IGFs, in serum approximately 75 % of circulating IGF-I and IGF-II bind to IGFBP3 and the co-carrier acid labile subunit (ALS). IGF-II binds to three receptors, and the binding to IGFIR promotes cell proliferation, survival, differentiation, and migration as well as metabolic function of IGF-II. Embryonic stem cell differentiation into endothelial cells is promoted by the binding of IGF-II to IGFR1. IGF-II binding to IGF-IIR induces internalization and clearing of IGF-II. Osteogenic differentiation and bone formation is enhanced by IGF-II through bone morphogenetic protein-9 (BMP-9). Polymorphisms of IGF-II are associated with obesity, cardiovascular risk factors, and hypertension.

Poids moléculaire: The 67 amino acid recombinant protein has a predicted molecular mass of approximately 7.4 kDa. The DTT-reduced and non-reduced protein migrate at approximately 9 kDa by SDS-PAGE. The N-terminal amino acid is Ala.
