胰岛素样生长因子1受体(英語:insulin-like growth factor 1,IGF-1R)是人类细胞表面发现的蛋白质,是激素胰岛素样生长因子1(IGF-1)的细胞表面受体,属于酪氨酸激酶受体家族。其配体IGF-1,是一种在分子结构上与多肽类激素胰岛素类似的激素,在生长发育和成人的合成代谢中有重要作用,可引起骨骼肌或其他组织的过度增殖。完全缺失IGF-1受体的小鼠会在生长发育到一定阶段时死亡,并伴随有体重急剧下降,带有单个IGF-1R等位基因缺失的小鼠仍能正常发育,但存在约15%的体重减少,这表明了此受体强烈的生长促进作用。

相互作用

胰岛素样生长因子1受体可与下列蛋白质相互作用

调控

There is evidence to suggest that IGF1R is negatively regulated by the microRNA miR-7.[17]
