This entry represents a small family of uncharacterised protein found in bacteria. They are predicted to adopt alpha+beta structure defined as beta(2)alpha(2)beta(2) structural elements in which the beta-strands form an antiparallel beta-sheet.The function of these proteins is unknown.

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.
