General Comments
This is a bromodomain-containing protein that is involved in chromatin modification [7]. Abnormally high levels of ATAD2 expression in a wide variety of unrelated patient cancer samples correlates with poor prognosis and disease recurrence [4,6,9]. Design of selective ATAD2 inhibitors as novel anti-cancer agents is being pursued [1,8].
