Profiling Genome-wide Chromatin Methylation with Engineered Posttranslation Apparatus within Living Cells


ABSTRACT: We have engineered the chromatin-modifying apparatus and formulated a novel technology, termed Clickable Chromatin Enrichment with parallel DNA sequencing (CliEn-seq), to probe genome-wide chromatin modification within living cells. Examine (E)-hex-2-en-5-ynylation mediated by engineered G9a Y1154A and GLP1 Y1211A in HEK293T cells.

Protein methyltransferases (PMTs) have emerged as important epigenetic regulators in myriad biological processes in both normal physiology and disease conditions. However, elucidating PMT-regulated epigenetic processes has been hampered by ambiguous knowledge about in vivo activities of individual PMTs particularly because of their overlapping but nonredundant functions. To address limitations of conventional approaches in mapping chromatin modification of specific PMTs, we have engineered the c  ...[more]
