    • ...However, several Drosophila piRNA pathway mutations have been reported to modify position effect variegation (PEV) (Brower-Toland et al., 2007; Pal-Bhadra et al., 2002; Pal-Bhadra et al., 2004), which is linked to spreading of transcriptionally silent heterochromatin from pericentric and telomeric regions (Girton and Johansen, 2008)...
    • ...Piwi protein also binds to heterochromatin in somatic cells, and interacts with Heterochromatin protein-1 (HP1) in yeast two-hybrid and immunoprecipitation assays (Brower-Toland et al., 2007)...
    • ...Transposon Silencing and Gene Expression The piRNA pathway is required for transposon silencing in the Drosophila female germline (Vagin et al., 2006) but has also been implicated in heterochromatic gene silencing in somatic cells (Brower-Toland et al., 2007; Pal-Bhadra et al., 2002; Pal-Bhadra et al., 2004)...

    • ...Recent experiments performed in flies demonstrate that PIWI interacts physically with the HP1 protein by virtue of the presence of the PxVxV domain [26]...
    • ...However, piwi mutations also have effects in somatic cells and the PIWI protein has been demonstrated to be present in the soma and piRNAs have been detected in somatic tissues [26,36]...

    • ...We also believe that studies of additional classes of REST interacting factors, such as multifunctional heterochromatin binding proteins (for example, Heterochromatin protein 1, which interacts with G9a [41]), DNA methylation effectors (for example, MeCP2, which recognizes methyl-DNA [58]) and specific subclasses of short and longer non-coding RNAs that may promote sequencespecific chromatin-modifications [59,60], will provide additional ...
