Protein Structure
UniProt Annotation
Function 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. May play a role in synapse maturation. {ECO:0000269PubMed:21076856, ECO:0000269PubMed:24132240}.
Subcellular Localization Secreted.
Disease Associations Insulin-like growth factor I deficiency (IGF1 deficiency) [MIM:608747]: Autosomal recessive disorder characterized by growth retardation, sensorineural deafness and mental retardation. {ECO:0000269PubMed:8857020}. Note=The disease is caused by mutations affecting the gene represented in this entry.
