A drug known as brefeldin A blocks the transfer of proteins to this organelle, while vesicles bound for it tend to be coated with either COP I or COP II.  
A drug known as brefeldin A blocks the transfer of proteins to this organelle, while vesicles bound for it tend to be coated with either COP I or COP II.  The current paradigm for its sorting abilities is explained by the "maturational model", which states that proteins from the endoplasmic reticulum enter its cis face and are packaged in its cisternae, after which they are transported out of the trans face.  Composed of a stack of flattened sacks, FTP, identify this cellular organelle, an apparatus named after an Italian anatomist.
