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}.
