This family includes uncharacterised proteins predominantly found in Proteobacteria, such as [swissprot:Q9I380] from Pseudomonas aeruginosa. This protein folds into a five-stranded antiparallel beta -sheet sandwiched between two short alpha-helices [[cite:PUB00065044]].

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.
