Insulin-like growth factor I deficiency (IGF1 deficiency) [MIM:608747]: Autosomal recessive disorder characterized by growth retardation, sensorineural deafness and mental retardation. {ECO:0000269|PubMed:8857020}. Note=The disease is caused by mutations affecting the gene represented in this entry.

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 (PubMed:21076856, PubMed:24132240). Ca(2+)-dependent exocytosis of IGF1 is required for sensory perception of smell in the olfactory bulb (By similarity). 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 (PubMed:19578119, PubMed:22351760, PubMed:23696648, PubMed:23243309). {ECO:0000250|UniProtKB:P05017, ECO:0000269|PubMed:19578119, ECO:0000269|PubMed:21076856, ECO:0000269|PubMed:22351760, ECO:0000269|PubMed:23243309, ECO:0000269|PubMed:23696648, ECO:0000269|PubMed:24132240}.
