    4. Together with Egg, Wde (Windei) localizes to euchromatin, is enriched on chromosome 4, and binds to the Painting of fourth (POF) protein.
      Title: Windei, the Drosophila homolog of mAM/MCAF1, is an essential cofactor of the H3K9 methyl transferase dSETDB1/Eggless in germ line development.
    5. These results suggest a balancing mechanism for the regulation of the fourth chromosome where POF and HP1 competitively bind at increasing levels with increased transcriptional activity.

    7. There is a balancing mechanism involving POF and HP1 that provides a feedback system for fine-tuning expression status of genes on the 4th chromosome.
