SETDB1 (SET domain bifurcated-1) is a histone H3-lysine 9 (H3K9)-specific methyltransferase that mediates heterochromatin formation and repression of target genes. Despite the assumed functional link between DNA methylation and SETDB1-mediated H3K9 trimethylations, several studies have shown that SETDB1 operates autonomously of DNA methylation in a region- and cell-specific manner. This study analyzes SETDB1-null HAP1 cells through a linked methylome and transcriptome analysis, intending to explore genes controlled by SETDB1-involved DNA methylation.
