Abstract |
Polycomb Repressive Complex2 maintains a predetermined state of transcription which constitutes a cellular memory stable over many cell divisions. Since this complex acts through the regulation of chromatin structure, it is important to understand how it is recruited to chromatin. The specific target sequences of this complex such as PRE (polycomb repressive element) have not been completely recognized in human genome. In this study, we have compared the target sequences of this complex with non-target genes in tumor cell lines. Through in silico and statistical analyses, we have identified some motifs which are over-represented in target genes against non-target genes. Analyzing these motifs shows some transcription factors which are potential recruiters of Polycomb repressive complex2.
