This protein family is a domain of unknown function. The precise function of this protein domain remains to be elucidated. This domain family is found in eukaryotes, and is typically between 64 and 79 amino acids in length. There are two conserved sequence motifs: QNAQ and HHH. In humans, it is found in the position, chromosome 21 open reading frame 58.

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.
