A dimeric protein complex that contains the co-factors for the ATPase VCP/p97 (Cdc48p in budding yeast). In mammals, this complex consists of UFD1L (UFD1) and NPLOC4 (NPL4). In budding yeast, the complex is a dimer of Ufd1p and Npl4p. [ http://www.ncbi.nlm.nih.gov/pubmed/10811609 GOC:PARL http://www.ncbi.nlm.nih.gov/pubmed/17289586 GOC:bf ]
Synonyms: Ufd1/Npl4 complex UFD1L-NPLOC4 complex Npl4p-Ufd1p complex Ufd1-Npl4 binary complex Ufd1-Npl4 cofactor complex
