Direct interactions between HDA1, HDA2, and HDA3.
35S-Methionine-labeled HDA1, HDA2, and HDA3 were incubated
with GST (lanes 2, 5, and 8) or GST-HDA1 (lanes 3, 6, and 9) and
immobilized on glutathione-Sepharose beads.
35S-Methionine-labeled HDA2 was incubated with GST (lane
11) and GST-HDA3 (lane 12). The interactions were analyzed according to
Materials and Methods.
