This domain is found in uncharacterised proteins from plants. It is predicted to adopt a structure consisting of a mixed beta-sheet and alpha-helices packed on both sides with unique topology. It contains a highly conserved sequence motif RxKxRKG that contributes to the formation of a highly basic surface patch.

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.
