WWE domains are characterized by the presence of a Trp-Trp-Glu region, which is important for PARP14 protein structure stabilization. WWE domains can bind to ADP-Ribose derivatives, including iso-ADP-ribose, a molecule specifically found in PAR and promote interactions with ubiquitinated proteins. The PARP14 WWE domain, however, is unable to bind to any ADP-ribose derivatives and whether it interacts with iso-ADP ribose or ubiquitinated targets is unknown.
