Carbohydrate-binding ability of a recombinant protein containing the DM9 motif from Drosophila melanogaster.

Proteins containing DM9 motifs, which were originally identified in the Drosophila melanogaster genome, are widely distributed in various organisms and are assumed to be involved in their innate immune response. In this study, we produced a recombinant protein of CG13321 (rCG13321) from D. melanogaster, which consists of four DM9 motifs, in Escherichia coli cells.
