This entry represents a domain found in uncharacterised bacterial proteins. It is predicted to fold into a small alpha/beta structure composed of beta-hairpin and array of helices packed on it. This domain is usually found associated with a pair of P-loop domains with the typical for helicases arrangement.

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.
