SETDB2 (CLLD8/KMT1F) functions as a histone H3K9 trimethyltransferase at interspersed repetitive elements and centromere-associated repeats, recruits heterochromatin protein 1 (HP1) to centromeres, and its depletion causes loss of CENP proteins and delayed mitosis, indicating a role in chromosome condensation and segregation. |

Setdb2 regulates trained immunity through two distinct mechanisms: (1) positively regulating glycolytic and inflammatory genes via enhancer-promoter looping independently of its enzymatic activity, and (2) repressing interferon response genes through increased H3K9me3 at promoters; pathogenic training activates both, while sterile inflammatory stimuli activate only the chromatin-looping mechanism. |
