 === Stimulating interaction : IGF-1 - IGF-1R ===
-'''Insulin-like Growth Factor 1 Receptor''' ('''IGF-1R''') is a transmembrane protein receptor. It is composed of two alpha subunits and two tyrosine beta subunits. Both alpha subunits are cysteine-rich region and therefore linked with a disulfide bond. Ligand-binding on alpha subunit induces activation of beta subunit by autophosphorylation. It further leads to activation of the Akt and mTor pathways inside the cell.

 Due to their homology sequences, the three members of the '''insulin protein family''': IGF-1, IGF-2 and Insulin can interact with one another of the different receptors. Hence, Insulin binds to IGF1R following the same mechanism and activated the intracellular pathways in the same way IGF1 does.
