Abstract
We report on crystal structures of a carbohydrate recognition domain (CRD) of human C-type lectin receptor blood dendritic cell antigen-2 (BDCA2). Three different crystal forms were obtained at 1.8-2.3 A resolution. In all three, the CRD has a basic C-type lectin fold, but a long loop extends away from the core domain to form a domain-swapped dimer. The structures of the dimers from the three different crystal forms superimpose well, indicating that domain swapping and dimer formation are energetically stable. The structure of the dimer is compared with other domain-swapped proteins, and a possible regulation mechanism of BDCA2 is discussed.
