Many newly synthesized proteins undergo a sequence of enzymatic modifications that enable them to do their jobs better. This process occurs within a series of membrane-bound structures called 'cisternae' that form the Golgi apparatus—an organelle that packages proteins before they are sent to their destination. Akihiko Nakano, Yasuyuki Suda and colleagues at the RIKEN Center for Advanced Photonics have now gained important insights into how protein movement through the Golgi apparatus is regulated.
 
When new proteins are produced, they are deposited into cisternae on the 'cis' side of the Golgi. These proteins undergo a maturation process as they migrate toward the 'trans' side of the Golgi before being released into the cell as fully processed proteins -
