Disease[IGF1A_HUMAN] Defects in IGF1 are the cause of insulin-like growth factor I deficiency (IGF1 deficiency) [MIM:608747]. IGF1 deficiency is an autosomal recessive disorder characterized by growth retardation, sensorineural deafness and mental retardation. Function[IGF1A_HUMAN] 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 rat 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.[1] Evolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMedThe solution structure of human insulin-like growth factor 1 has been investigated with a combination of nuclear magnetic resonance and restrained molecular dynamics methods. The results show that the solution structure is similar to that of insulin, but minor differences exist. The regions homologous to insulin are well-defined, while the remainder of the molecule exhibits greater disorder. The resultant structures have been used to visualize the sites for interaction with a number of physiologically important proteins.
