Transcriptional activator involved in gene imprinting. Catalyzes the release of 5-methylcytosine (5-meC) from DNA by a glycosylase/lyase mechanism. Allows the expression of the maternal copy of the imprinted MEA gene before fertilization, possibly by antagonizing or suppressing DNA methylation on target promoter. Probably acts by nicking the MEA promoter. Required for stable reproducible patterns of floral and vegetative development. Source: Recombinant protein corresponding to aa1-320 from arabidopsis thaliana DME, fused to His-SUMO-Tag at N-terminal, expressed in E. coli.
