IRS2（insulin receptor substrate 2、インスリン受容体基質2）は、ヒトではIRS2遺伝子によってコードされるタンパク質である^[5]。

機能[編集]

IRS2遺伝子はIRS２タンパク質をコードする。IRS2は細胞質のシグナル伝達分子であり、多様な受容体型チロシンキナーゼと下流のエフェクター分子との間のアダプタータンパク質として、インスリン、IGF-1や他のサイトカインの効果を媒介する。IRS2はインスリン受容体の刺激に伴ってリン酸化されるほか、IL-4処理に応答してIL-4受容体関連キナーゼによってもリン酸化される^[6]。

IRS2を欠失したマウスは糖尿病の表現型を示すとともに^[7]、脳の重量が40％低下する^[8]。

相互作用[編集]

IRS2は次に挙げる因子と相互作用することが示されている。
