This is a protein of approximately 200 residues which is conserved from plants to humans [1]. It contains a highly conserved QFW motif close to the N-terminus and a DPPF motif in the centre. The DPPF motif is characteristic of N-6 adenine-specific DNA methylases, and this family is found in eukaryotes [2].
