CC -!- FUNCTION: The insulin-like growth factors, isolated from plasma, are
CC structurally and functionally related to insulin but have a much higher
CC growth-promoting activity. Acts as a ligand for IGF1R. Binds to the
CC alpha subunit of IGF1R, leading to the activation of the intrinsic
CC tyrosine kinase activity which autophosphorylates tyrosine residues in
CC the beta subunit thus initiatiating a cascade of down-stream signaling
CC events leading to activation of the PI3K-AKT/PKB and the Ras-MAPK
CC pathways. Binds to integrins. Its binding to integrins and subsequent
CC ternary complex formation with integrins and IGFR1 are essential for
CC IGF1 signaling. {ECO:0000250|UniProtKB:P05019}.
CC -!- SUBCELLULAR LOCATION: Secreted.
CC -!- SIMILARITY: Belongs to the insulin family. {ECO:0000305}.
