ZBP1(DAI) binds to double-stranded DNA in vitro and in vivo (Wang ZC et al 2008; Takaoka A et al 2007). N-teminus of ZBP1 contains two Z-DNA (Zalpha and Zbeta) and one B-DNA binding domains (D3 region). D3 region mediates initial binding of ZBP1 to DNA with subsequent stabilization provided by the Zalpha and Zbeta domains. All tree DNA-binding domains are required for ZBP1 full activation (Wang ZC et al 2008).

ZBP1 was reported to form multimer upon DNA binding that might facilitate innate immune responces (Wang ZC et al 2008; Ha SC et al 2008).
