In the cytosol the CT A1 chain stimulates adenylyl cyclase. The VCP(Ufd1-Npl4) complex mediates retrotranslocation of emerging ER proteins. While one group reported that VCP is required for CT retrotranslocation, another group concluded the opposite. We show that VCP is dispensable for CT retrotranslocation, however RNAi of either Ufd1 or Npl4 induces an increase in adenylyl cyclase activity induced by CT. RNAi of VCP, Ufd1 or Npl4 did not affect adenylyl cyclase activity induced by forskolin. These findings are coherent with our previous report showing that depletion of Ufd1-Npl4 accelerates ERAD of reporter substrates. To integrate contradictory results we propose a new model, where Ufd1-Npl4 is a negative regulator of retrotranslocation, delaying the retrotranslocation of ERAD substrates independently of its association with VCP."xsd:string |
