The website is about the Worldwide Protein Data Bank (wwPDB) and its mission to serve as a repository for information on protein structures. The site provides resources such as validation reports, tutorials, and dictionaries related to protein data deposition. It also highlights the task forces involved in validating different aspects of protein structure data, including X-ray validation and small-angle scattering. The website manages the archive of protein structure data since 1971 and ensures that this information is freely available to the public.
