A protein complex containing, in mammals, Derlin-1 and VCP-interacting membrane protein (VIMP). The complex links the p97/VCP-containing ATPase complex with Derlin-1 during translocation of protein substrates from the endoplasmic reticulum to the cytosol for degradation by the cytosolic proteasome.
