生物谷報道：復旦大學生物醫(yī)學研究院細胞分子生物學研究室管坤良教授和趙世民博士在5月2日出版的Cell發(fā)表了有關(guān)細胞信號傳導特異性研究前沿進展綜述：Substrate Selectivity APPLies to Akt.
信號傳導特異性的研究是目前國際信號傳導研究的熱點之一。細胞通過復雜的信號“分揀系統(tǒng)”將特定外部刺激產(chǎn)生的信號準確地傳達到細胞內(nèi)的相關(guān)功能執(zhí)行蛋白,，而且不改變細胞內(nèi)其它蛋白的功能,，進而達到一種外界刺激只引發(fā)特定的生理響應（如細胞的生長、凋亡等）的結(jié)果,。相關(guān)領(lǐng)域的研究突破可能為研制特異的抗癌藥物以及開發(fā)針對其它疾病的特異性藥物帶來新的希望,。（生物谷www.bioon.com)

Summary
The protein kinase Akt occupies a central position in multiple signaling pathways. Although numerous Akt substrates have been identified, less is known about the factors that regulate specific cellular responses to Akt signaling. In this issue, Schenck et al., 2008 demonstrate that the endosomal protein Appl1 modulates Akt's substrate selectivity to promote cell survival during zebrafish development.
