Abstract：
:Like the conductor of an orchestra, the Sec protein translocation channel is the platform needed to bring together the many different players required for the constitutive and obligatory process of protein transport. This conserved membrane channel, termed SecY in bacteria and Sec61 in eukaryotes, creates a ubiquitous protein-conducting pathway by which thousands of newly synthesized polypeptides make their way through the lipid bilayer. The channel is not a simple passive pore, however; it displays remarkable complexity by interacting with numerous soluble partners, including SecA, Syd, FtsY and the ribosome in bacteria. For several decades, scientists have been fascinated by the sophistication and versatility of this transport channel. In this review, we cover the current state of the field including some of the newest and most exciting findings on channel structure and mechanism of action.
