Insulin-Rezeptor-Substrat 2

Das vom IRS2-Gen kodierte ein Protein der Signaltransduktion. Es ist das Bindeglied verschiedener rezeptorgebundener Tyrosinkinasen und den intrazellulären Effektoren. Neben dem Insulinrezeptor vermittelt dieses Protein auch die Signale des IGF1-Rezeptors und verschiedener Zytokine. Mutationen werden mit einer Insulinresistenz und Typ 2 Diabetes in Verbindung gebracht.
