This family of uncharacterized proteins is found in various phages that infect bacterial hosts such as Bacillus, Staphylococcus, Enterococcus, Listeria, Lactobacillus, and Brochothrix species. The proteins in the family are typically 75 to 100 amino acids in length. The protein contains a small N-terminal domain represented by this entry followed by a C-terminal disordered region.

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.
