HBx 120 and 121 mutants fail to interact with ERCC2 and ERCC3 components of human TFIIH. (A) HBx and HBx mutants 120, 121, 124, and 125 were in vitro translated in the presence of 35S methionine and allowed to interact with the fusion protein of Mal-ERRCC2. Bound fractions are shown. (B) ERCC3 was in vitro translated in the presence of 35S-[methionine] and allowed to interact with GST (lane 1), GST-X (lanes 2), or GST HBx mutants Asp 113 (lane 3), Asp 118 (lane 4), Glu 120 (lane 5), Glu121 (lane 6) and double mutant Glu 120/121 (lane7).
