This family of proteins is functionally uncharacterised. This family of proteins is found in prokaryotes. Advanced homology-detection methods supported with superfamily-wide domain architecture and horizontal gene transfer analyses s have established this family to be a member of the PD-(D/E)XK superfamily.

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.
