Histone methyltransferases direct different degrees of methylation to define distinct chromatin domains.

abstract：:All nuclear transcription is interrupted during mitosis. We examined the role of human TTF2, an RNA polymerase (Pol) I and II termination factor, in mitotic repression of transcription elongation. We find that TTF2 levels rise in the cytoplasm in S and G2 and at the onset of mitosis TTF2 translocates into the nucleus....
