The mouse embryonic stem cells cDNA library was screened by yeast two-hybrid assay,some candidate molecules were get,including DDX39 DEAD (Asp-Glu-Ala-Asp box polypeptide 39, BAT1A(HLA-B-associated transcript 1A), NAC1 ( nucleus accumbens-1 ), BicD2 (bicaudal D homolog 2)、MLL3 (myeloid/lymphoid or mixed-lineage leukemia 3).
