Abstract:

The crystal structure of the dimerization domain of the V(D)J recombination-activating protein, RAG1, was solved using zinc anomalous scattering. The structure reveals an unusual combination of multi-class zinc-binding motifs, including a zinc RING finger and a C2H2 zinc finger, that together from a single structural domain. The domain also contains a unique zinc binuclear cluster in place of a normally mononuclear zinc site in the RING finger. Together, four zinc ions help organize the entire domain, including the two helices that form the dimer interface.
