Proteins that arrive from the ER are taken up by the cis Golgi and passed through the stack. As they travel through the Golgi, they are further modified (recall that proteins have already been modified by the addition of various molecules such as sugars or lipids in the ER). These modifications help mark them for their final destinations. They are then passed from the trans Golgi into vesicles that travel to their targets and deliver the proteins to the desired region of the cell.
