Graduate Student Theses, Dissertations, & Professional Papers
The ER-Golgi interface is a very dynamic environment that involves the movement of protein-loaded vesicles forward and backward. The movement of COPII-coated vesicles from the ER to the Golgi is the initial step in the movement of secreted, organellar, and cell surface proteins toward their final destinations. Many factors can regulate this step, including cytosolic calcium increases. In this study, we examined the effect of a transient calcium pulse on recruitment to ER exit sites of cargo proteins for ER export, the calcium-sensitive regulatory proteins apoptosis-linked gene 2 (ALG-2) and peflin, and the COPII outer coat subunits Sec31A and Sec13. …
