Limitations of the Current StudiesLimitations of the Current Studies
- Because of the nature of the IgA molecule, crystalizing this structure was not possible. Therefore, many of these structures are based on models and not actual crystal structures. Because ...., the models were depositable in the PDB. I tried to include other crystallographic data when available, supporting the proposed models- as the authors did in the original papers.
Questions for the FutureQuestions for the Future
- Because of the limitating resolution of these models, many details concerning the binding residues and residue interactions are left unknown. Crystallographic structure will yield further insights into the structure of IgA, the interactions between IgA and other molecules, and ....
