==Crystal Structure of the DNA-Binding Domain Zalpha of DLM-1 Bound to Z-DNA==
-
The first crystal structure of a protein, the Z alpha high affinity, binding domain of the RNA editing enzyme ADAR1, bound to left-handed Z-DNA, was recently described. The essential set of residues determined from this, structure to be critical for Z-DNA recognition was used to search the, database for other proteins with the potential for Z-DNA binding. We found, that the tumor-associated protein DLM-1 contains a domain with remarkable, sequence similarities to Z alpha(ADAR). Here we report the crystal, structure of this DLM-1 domain bound to left-handed Z-DNA at 1.85 A, resolution. Comparison of Z-DNA binding by DLM-1 and ADAR1 reveals a, common structure-specific recognition core within the binding domain., However, the domains differ in certain residues peripheral to the, protein-DNA interface. These structures reveal a general mechanism of, Z-DNA recognition, suggesting the existence of a family of winged-helix, proteins sharing a common Z-DNA binding motif.

== Function ==
 +
[https://www.uniprot.org/uniprot/ZBP1_MOUSE ZBP1_MOUSE] Participates in the detection by the host's innate immune system of DNA from viral, bacterial or even host origin. Plays a role in host defense against tumors and pathogens. Acts as a cytoplasmic DNA sensor which, when activated, induces the recruitment of TBK1 and IRF3 to its C-terminal region and activates the downstream interferon regulatory factor (IRF) and NF-kappa B transcription factors, leading to type-I interferon production. ZBP1-induced NF-kappaB activation probably involves the recruitment of the RHIM containing kinases RIPK1 and RIPK3.<ref>PMID:17618271</ref> <ref>PMID:19590578</ref>

== Publication Abstract from PubMed ==
 +
The first crystal structure of a protein, the Z alpha high affinity binding domain of the RNA editing enzyme ADAR1, bound to left-handed Z-DNA was recently described. The essential set of residues determined from this structure to be critical for Z-DNA recognition was used to search the database for other proteins with the potential for Z-DNA binding. We found that the tumor-associated protein DLM-1 contains a domain with remarkable sequence similarities to Z alpha(ADAR). Here we report the crystal structure of this DLM-1 domain bound to left-handed Z-DNA at 1.85 A resolution. Comparison of Z-DNA binding by DLM-1 and ADAR1 reveals a common structure-specific recognition core within the binding domain. However, the domains differ in certain residues peripheral to the protein-DNA interface. These structures reveal a general mechanism of Z-DNA recognition, suggesting the existence of a family of winged-helix proteins sharing a common Z-DNA binding motif.
