PROSITE documentation PDOC50908RWD domain profile
The RWD domain is a conserved region of about 110 amino acid residues, which has been identified in the mouse GCN2 eIF2α kinase and histidyl-tRNA synthetase and in presumed orthologs in other eukaryotic species from yeast to vertebrates. Additionally, it is also found in WD repeat containing proteins, yeast DEAD (DEXD)-like helicases, many RING-finger containing proteins, the UPF0029 uncharacterized protein family (see <PDOC00707>) and a range of hypothetical proteins. The RWD domain has been named after the better characterized RING finger (see <PDOC00449>) and WD repeat containing proteins (see <PDOC00574>) and DEAD-like helicaces (see <PDOC00039>). It has been proposed that the RWD domain might have a function in protein interaction [1].
The RWD domain is predicted to have an α/β secondary structure and is thought to be related to ubiquitin-conjugating enzymes (UBCc) domain, although the catalytic cysteine critical for ubiquitin-conjugating activity is not conserved in most members of the novel subfamily [1].
The profile we developed covers the entire RWD domain.
