METHOD OF SUPPRESSING GENE TRANSCRIPTION THROUGH HISTONE LYSINE METHYLATION

摘要

The present invention relates to methods of suppressing the transcriptional expression of one or more genes by methylating the chromatin histone proteins of the one or more genes. Specifically, a viral SET domain histone lysine mehtyltransferase (vSET or vSET-like protein) methylates lysine 27 of a gene's histone protein 3 (H3- K27) thereby suppressing the transcription of the gene.
