| Research Abstract |
A novel VCIP135 binding protein is identified as WAC. WAC directly binds to VCIP135, and activates deubiquitinase activity of VCIP135 in vitro. WAC localizes to the Golgi, and functions as an essential factor for Golgi biogenesis. Interestingly, in Golgi reassembly, WAC functions only in p97/p47 membrane fusion pathway, but not in p97/p37 membrane fusion pathway. On the other hand, WAC has no function in ER biogenesis at all. It is suggested that ubiquitin signaling mediated by VCIP135/WAC plays a specific role in Golgi biogenesis, especially in mitosis.
