PR (PRD1-BF1-RIZ1 homologous) domain-containing 16 (PRDM16) drives a brown fat
differentiation program, but the mechanisms by which PRDM16 activates brown
fat-selective genes have been unclear. Through chromatin immunoprecipitation
(ChIP) followed by deep sequencing (ChIP-seq) analyses in brown adipose tissue
(BAT), we reveal that PRDM16 binding is highly enriched at a broad set of brown
fat-selective genes. Importantly, we found that PRDM16 physically binds to MED1,
a component of the Mediator complex, and recruits it to superenhancers at brown
fat-selective genes. PRDM16 deficiency in BAT reduces MED1 binding at PRDM16
target sites and causes a fundamental change in chromatin architecture at key
brown fat-selective genes. Together, these data indicate that PRDM16 controls
chromatin architecture and superenhancer activity in BAT.
