This presumed domain has been predicted to contain three alpha helices. The domain was named the WIYLD domain based on the pattern of most conserved residues [1]. It binds ubiquitin. In the Arabidopsis thaliana histone-lysine N-methyltransferase SUVR4, Swiss:Q8W595, binding of ubiquitin to this domain stimulates enzymatic activity and converts its activity from a strict dimethylase to a di/trimethylase [2].
