Research Abstract |
COPII vesicles are formed at the ER exit sites, which mediate the ER-to-Golgi traffic. Sec16 acts as a key factor for ERES formation as well as COPII-mediated transport. Here we have shown that Sec16 is self-assembled to form a homooligomer on the membranes. In addition, we find that Sec16 negatively regulates activation of Sar1 GTP hydrolysis by COPII coat proteins.
