This entry represents a family of uncharacterised proteins found in both bacteria and archaea. The proteins are predominantly found in Actinomycetes and Halobacteria. The proteins in this family are approximately 300 to 400 amino acids in length.

These families have been collected together in the Pfam database using the prefix DUF followed by a number, with examples being DUF2992 and DUF1220. As of 2019, there are almost 4,000 DUF families within the Pfam database representing over 22% of known families. Some DUFs are not named using the nomenclature due to popular usage but are nevertheless DUFs.
