This entry represents the C-terminal domain from a family of uncharacterised proteins from halophilic archaea. The proteins in this family are predominantly found in the class Halobacteria, which includes families such as Natrialbaceae, Haloferacaceae, and Haloarculaceae. The proteins in this family are generally around 270-330 amino acids in length. This domain is found associated with a peptidase M23 family like domain at the N-terminus.

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.
