(A) The liver protein lysates from control and 14-day LCA treated livers were subjected to IP using anti-Matα1, anti-c-Myc, anti-c-Maf and MafG, followed by mass spectrometry. The table shows a small subset of scores representing potential interacting proteins of interest. NS=no score. The liver protein lysates from control and 14-day LCA were immunoprecipitated (IP) with either antibodies to (B) Matα1, (C) c-Myc, (D) c-Maf, or (E) MafG and then subjected to Western blotting (IB) for Matα1, c-Myc, c-Maf, Maf, Mnt and Max. Histone H3 served as loading control. (F) In vitro pull down assay using immobilized Matα1 (left) or c-Myc (right). Matα1 directly interact with c-Myc, Max, Maf and MafG (left), and c-Myc directly interact with Max, Maf and MafG (right). Results represent a total of at least 3 independent experiments done in duplicate.
