This entry represents a domain from a family of uncharacterised proteins in archaea. The proteins are predominantly found in the class Halobacteria, which includes various genera such as Halorubrum, Haloarcula, and Natrialba. The domain is typically found in proteins ranging from 59 to 484 amino acids in length. The proteins in this family are integral membrane proteins usually with four transmembrane helices.

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.
