| Scientific Background: | Giantin, the largest Golgi membrane protein, is C-terminally anchored to cis- and medial-Golgi membranes and forms a long ~250nm coiled-coil rod that directly interacts with microtubules in a cell-cycle regulated way. It is an excellent marker for mammalian golgi complex. Giantin plays also a role in docking COPI vesicles to Golgi membranes. It is speculated that after mitosis giantin aids in guiding vesiculated Golgi membranes to the microtubule organizing center to reform a new Golgi apparatus. |
