•Modifies, concentrates, and packages proteins and lipids received from rough ER •Three steps are involved: 1. Transport vesicles from ER fuse with cis (inner) face of Golgi 2. Proteins or lipids taken inside are further modified, tagged, sorted, and packaged 3. Golgi is “traffic director,” controlling which of A pivotal advance in identifying the molecular basis of organelle movement on microtubules was the discovery of the microtubule based motor proteins, kinesin and cytoplasmic dynein [23]. These proteins appear to bind microtubules and transduce chemical energy (ATP) into mechanical work to power polarized movement of the mitochondria along ...

Proteins are first translated at the endoplasmic reticulum, then are transported to the Golgi apparatus in vesicles to be packaged and shipped. Many of the proteins that enter the secretory pathway require chaperones to help with folding or post-translational modification to function properly.
Importantly, recruitment of endoplasmic reticulum (ER) proteins by vacuoles containing the sidJ mutant was considerably delayed in both mammalian and amoeba cells. Our results suggest that SidJ modulates host cellular pathways, contributing to the trafficking or retention of ER-derived vesicles to L. pneumophila vacuoles.
