該基因編碼一個信號通路的組成部分，該信號通路調節細胞生長以響應營養素和胰島素水平。編碼蛋白與mtor激酶形成化學計量復合物，并與真核起始因子4e結合蛋白-1和核糖體蛋白s6激酶相關。該蛋白正調控下游效應核糖體蛋白s6激酶，負調控mtor激酶。已發現該基因編碼不同亞型的多個轉錄變體。[由RefSeq提供，2009年9月]
This gene encodes a component of a signaling pathway that regulates cell growth in response to nutrient and insulin levels. The encoded protein forms a stoichiometric complex with the mTOR kinase, and also associates with eukaryotic initiation factor 4E-binding protein-1 and ribosomal protein S6 kinase. The protein positively regulates the downstream effector ribosomal protein S6 kinase, and negatively regulates the mTOR kinase. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2009]
