| 1 | Let’s talk about Secs: Sec61, Sec62 and Sec63 in signaltransduction, oncology and personalized medicine显示文摘The heterotrimeric Sec61 complex and the dimeric Sec62/Sec63 complex are located in the membrane of the human endoplasmic reticulum(ER)and play a central role in translocation of nascent and newly synthesized precursor polypeptides into the ER.This process involves targeting of the precursors to the membrane and opening of the polypeptide conducting Sec61 channel for translocation.Apart from this central role in the intracellular transport of polypeptides,several studies of the last decade uncovered additional functions of Sec proteins in intracellular signaling:Sec62 can induce ER-phagy in the process of recovery of cells from ER stress and the Sec61 channel can also act as a passive ER calcium leak channel.Furthermore,mutations,amplifications and an overexpression of the SEC genes were linked to various diseases including kidney and liver diseases,diabetes and human cancer.Studies of the last decade could not only elucidate the functional role of Sec proteins in the pathogenesis of these diseases,but also demonstrate a relevance of Sec62 as a prognostic and predictive biomarker in head and neck cancer,prostate and lung cancer including a basis for new therapeutic strategies.In this article,we review the current understanding of protein transport across the ER membrane as central function of Sec proteins and further focus on recent studies that gave first insights into the functional role and therapeutic relevance of Sec61,Sec62 and Sec63 in human diseases. | Maximilian Linxweiler Bernhard Schick Richard Zimmermann | 2017 | Signal Transduction and Targeted Therapy2017，2，1： | 8 |
